Using a piece of wire or string, tie the caliper to the front suspension coil spring to avoid placing any strain on the hydraulic brake hose. 7Use chalk or paint to mark the relationship of the disc to the hub, then remove the two screws securing the brake disc to the hub and remove the disc. If the disc is a tight fit on the hub it can be drawn off by screwing two bolts into the jacking holes provided (see illustrations). Refitting 8Refitting is the reverse of the removal procedure, noting the following: a) Ensure that the mating surfaces of the disc and hub are clean and flat. b) Align (if applicable) the marks made on removal. c) If a new disc has been fitted, use a suitable solvent to wipe any preservative coating from the disc before refitting the caliper. d) Tighten the disc retaining screws, caliper bracket bolts and roadwheel nuts to their specified torque wrench settings. 14 Pressure regulating valve- testing, removal and refitting 3 Testing 1The pressure regulating valve is mounted on the right-hand side of the engine compartment bulkhead. 2Specialist equipment is required to check valve performance. If the valve is thought to be faulty, the vehicle should be taken to a suitably equipped Rover dealer for testing. However, in the event of an internal failure, brake fluid will seep from the plug on the front face of the valve which is situated directly above the lower two hose unions (see illustration). Repairs are not possible and, if faulty, the valve must be renewed. Removal 3Disconnect the sender unit wiring connector and unscrew the master cylinder reservoir filler cap. Place a piece of polythene over the filler neck and securely refit the cap (taking care not to damage the sender unit). This will minimise brake fluid loss during subsequent operations. As an added precaution, place absorbent rags beneath the pressure regulating valve brake pipe unions. 4Wipe clean the area around the brake pipe unions on the pressure regulating valve, then make a note of how the pipes are arranged for reference on refitting. Unscrew the union nuts and carefully withdraw the pipes. Plug or tape over the pipe ends and valve orifices to minimise the loss of brake fluid and to prevent the entry of dirt into the system. Wash off any spilt fluid immediately with cold water. 5Slacken the two bolts which secure the valve to the bulkhead and remove it from the engine compartment. Refitting 6Refit the pressure regulating valve to the bulkhead and tighten its mounting bolts securely. 7Wipe the brake pipe unions clean and refit them to the valve, using the notes made ondismantling to ensure they are correctly positioned. Tighten the union nuts to the specified torque. 8Remove the polythene from the master cylinder reservoir filler neck and bleed the complete hydraulic system. 15 Rear brake shoes- inspection Refer to Chapter 1. 16 Rear brake shoes- renewal 3 Warning: Brake shoes must be renewed on both rear wheels at the same time. Never renew the shoes on only one wheel as uneven braking may result. Removal 1Remove the brake drum. 2Working carefully and noting all precautions, remove all traces of brake dust from the brake drum, backplate and shoes. 3Measure the thickness of friction material remaining on each brake shoe at several points. If either shoe is worn at any point to the specified minimum thickness or less, all four shoes must be renewed as a set. Also, the shoes should be renewed if any are fouled with oil or grease as there is no satisfactory way of degreasing friction material once contaminated. 4If any of the brake shoes are worn unevenly or fouled with oil or grease, trace and rectify the cause before reassembly. 5To remove the brake shoes, first remove the shoe retainer springs and pins, using a pair of pliers to press in each retainer clip until it can be rotated through 90º and released. Ease the shoes out one at a time from the Braking system 9•11 14.2 In the event of failure, fluid will seep from pressure regulating valve plug (arrowed) 13.7b Drawing off a disc using two 8 mm bolts13.7a Removing disc retaining screws (jacking holes arrowed) 9 1689 Rover 214 & 414 Updated Version 09/97
lower pivot point to release the tension of the return spring, then disconnect the lower return spring from both shoes. Ease the upper end of both shoes out from their wheel cylinder locations, taking great care not to damage the wheel cylinder seals, and disconnect the handbrake cable from the trailing shoe. The brake shoe and adjuster strut assembly can now be manoeuvred out of position and away from the backplate (see illustrations). Do not depress the brake pedal until the brakes are reassembled. Wrap a strong elastic band around the wheel cylinder pistons to retain them. 6With the brake shoe assembly on the worksurface, make a note of the fitted positions of the adjuster strut and springs to use as guide on reassembly (see illustration). Carefully ease the adjuster strut from its slot in the trailing shoe and remove the short spring which secures the two components together. Detach the upper return spring and separate the shoes and strut. 7Examine the adjuster strut assembly for signs of wear or damage, paying particular attention to the adjuster quadrant and knurled wheel. If damaged, the strut assembly must be renewed. Renew all the brake shoe return springs regardless of their apparent condition. 8Peel back the rubber protective caps and check the wheel cylinder for fluid leaks or other damage. Check that both cylinder pistons are free to move easily. Fitting 9Prior to fitting, clean the backplate and apply a thin smear of high-temperature brake grease (silicone- or PBC/Poly Butyl Cuprysil- based) or anti-seize compound (eg Holts Copaslip) to all those surfaces of the backplate which bear on the shoes, particularly the adjuster and the wheel cylinder pistons. Do not allow lubricant to foul the friction material. 10Ensure the handbrake lever stop on the trailing shoe is correctly engaged with the lever and is pressed tight against the brake shoe (see illustration). 11Fully extend the adjuster strut quadrant and fit the leading brake shoe into the adjuster strut slot, ensuring that the strut spring and 9•12 Braking system 16.10 Ensure handbrake stop lever is correctly located16.6 Correct fitted positions of adjuster strut and springs16.5d . . . and manoeuvre shoe and adjuster strut assembly away from backplate 16.5c . . . unhook lower return spring . . .16.5b Remove brake shoe retainer springs . . . 16.5a Rear drum brake assembly 1 Brake drum 2 Drum retaining screw 3 Backplate 4 Lower return spring 5 Brake shoe 6 Retainer pin and spring7 Adjuster strut 8 Strut spring 9 Upper return spring 10 Wheel cylinder retaining bolt11 Bleed screw 12 Backplate mounting bolt 13 Seal 14 Wheel cylinder 15 Grommet 1689 Rover 214 & 414 Updated Version 09/97
knurled wheel are situated on the underside of the strut assembly. Using a screwdriver, move the quadrant away from the knurled wheel and set it in the minimum adjustment position. 12Fit the upper return spring to its respective location on the leading shoe. Fit the trailing shoe to the upper return spring and carefully ease the shoe into position in the adjuster strut slot. Once in position, fit the small spring which secures the trailing shoe to the strut assembly. 13Remove the elastic band fitted to the wheel cylinder and manoeuvre the shoe and strut assembly into position on the backplate. Locate the upper end of both shoes with the wheel cylinder pistons and fit the handbrake cable to the trailing shoe operating lever. Fit the lower return spring to both shoes and ease the shoes into position on the lower pivot point. 14Tap the shoes to centralise them with the backplate, then refit the shoe retainer pins and springs and secure them in position with the retainer clips. Check that the adjuster quadrant is still in the minimum adjuster position and if necessary, reset as follows. Place a block of wood between the trailing shoe and hub, to prevent the shoe moving forwards, then lever the leading shoe away from the hub to release the brake shoe return spring pressure on the adjuster quadrant. With the shoe held in this position, reset the quadrant to the minimum adjustment setting (see illustration). Once the adjuster strut is correctly set, ease the leading shoe back into position then remove the block of wood and check that the shoes are still central.15Refit the brake drum and repeat the above operation on the remaining rear brake assembly. 16On completion, apply the footbrake repeatedly to set the shoe-to-drum clearance, until normal (non-assisted) brake pedal operation returns. 17Check handbrake cable operation and, if necessary, adjust as described in Chapter 1. 18Refit the roadwheels then lower the vehicle to the ground and tighten the roadwheel nuts to the specified torque. 19Check the hydraulic fluid level. 17 Rear brake drum- removal, inspection and refitting 2 Note:If either brake drum requires renewal, both should be renewed at the same time to ensure even and consistent braking. Removal 1Chock the front wheels then jack up the rear of the vehicle and support it on axle stands. Remove the appropriate rear wheel. 2Use chalk or paint to mark the relationship of the drum to the hub. 3With the handbrake firmly applied to prevent drum rotation, unscrew the drum retaining screws (see illustration). Fully release the handbrake cable and withdraw the drum. 4If the drum will not pull away, first check that the handbrake is fully released. If the drum will still not come away, remove the grommet from the rear of the backplate and, using a small screwdriver, disengage the handbrake lever stop from behind the lever to increase the shoe to drum clearance. If removal still proves troublesome, the brake drum can be drawn off by screwing two bolts into the jacking holes provided (see illustrations). Inspection 5Working carefully, remove all traces of brake dust from the drum. Avoid inhaling the dust as it is injurious to health. 6Scrub clean the outside of the drum and check it for obvious signs of wear or damage such as cracks around the road- wheel stud holes. Renew the drum if necessary. 7Examine carefully the inside of the drum. Light scoring of the friction surface is normal but if heavy scoring is found, the drum must be renewed. It is usual to find a lip on the drum’s inboard edge which consists of a mixture of rust and brake dust. This should be scraped away to leave a smooth surface which can be polished with fine (120 to 150 grade) emery paper. If, however, the lip is due to the friction surface being recessed by excessive wear, then the drum must be renewed. 8If the drum is thought to be excessively worn or oval, its internal diameter must be measured at several points by using an internal micrometer. Take measurements in pairs, the second at right angles to the first, and compare the two to check for signs of ovality. Provided that it does not enlarge the drum to beyond the specified maximum diameter, it may be possible to have the drum refinished by skimming or grinding but if this is not possible, the drums on both sides must be renewed . Refitting 9Refitting is the reverse of the removal procedure, noting the following: a) On fitting a new brake drum, use a suitable solvent to remove any preservative coating that may have been applied to its interior. b) Use a clean wire brush to remove all traces of dirt, brake dust and corrosion from the mating surfaces of the drum and the hub flange. c) Align (if applicable) the marks made on removal. d) Tighten the drum retaining screws and the roadwheel nuts to their specified torque wrench settings.

18 Rear wheel cylinder- removal, overhaul and refitting 4 Note:Before attempting to overhaul a rear wheel cylinder, check the price and availability of individual components and the price of a new or reconditioned unit, as overhaul may not be viable on economic grounds alone. Removal 1Remove the brake shoes. 2Minimise fluid loss by removing the master cylinder reservoir cap and then tightening it down onto a piece of polythene to obtain an airtight seal (taking care not to damage the sender unit), or by using a brake hose clamp, a G-clamp or a similar tool to clamp the flexible hose. 3Wipe away all traces of dirt around the brake pipe union at the rear of the wheel cylinder and unscrew the union nut. Carefully ease the pipe out of the wheel cylinder and plug or tape over its end to prevent dirt entry (see illustration). 4Unscrew the two wheel cylinder retaining bolts from the rear of the backplate and remove the cylinder, noting the rubber sealing ring which is fitted between the cylinder and backplate. Overhaul 5Remove the wheel cylinder from the vehicle and clean it thoroughly. 6Mount the wheel cylinder in a soft-jawed vice and remove the rubber protective caps. Extract the piston assemblies. 7Thoroughly clean all components using only methylated spirit, isopropyl alcohol or clean hydraulic fluid as a cleaning medium. Never use mineral-based solvents such as petrol or paraffin which will attack the hydraulic system’s rubber components. Dry the components immediately using compressed air or a clean, lint-free cloth. 8Check all components and renew any that are worn or damaged. Check particularly the cylinder bore and pistons. The complete assembly must be renewed if these arescratched, worn or corroded. If there is any doubt about the condition of the assembly or of any of its components, renew it. Remove the bleed screw and check that the fluid entry port and bleed screw passages are clear. 9If the assembly is fit for further use, obtain a repair kit. Renew the rubber protective caps, dust caps and seals disturbed on dismantling, these should never be re-used. Renew also any other items included in the repair kit. 10On reassembly, soak the pistons and the new seals in clean hydraulic fluid. Smear clean fluid on the cylinder bore surface. 11Fit the new seals to their pistons using only the fingers to manipulate them into the grooves. Ensure that all components are refitted in the correct order and the right way round. 12Insert the pistons into the bore using a twisting motion to avoid trapping the seal lips. Apply a smear of rubber lubricant to each piston before fitting the new rubber protective caps. Refitting 13Fit a new sealing ring to the rear of the wheel cylinder and place the cylinder in position on the backplate. 14Refit the wheel cylinder retaining bolts and tighten them to the specified torque. 15Tighten the brake pipe union nut and, if necessary, remove the clamp from the brake hose. 16Refit the brake shoes. 17Bleed the hydraulic braking system. If precautions were taken to minimise fluid loss, it should only be necessary to bleed the relevant rear brake. On completion, check that both footbrake and handbrake function correctly before taking the vehicle on the road. 19 Rear brake pads- inspection Refer to Chapter 1. 20 Rear brake pads- renewal 2 Warning: Renew both sets of rear brake pads at the same time. Never renew the pads on only one wheel as uneven braking may result. Removal 1Chock the front wheels then jack up the rear of the vehicle and support on axle stands. Remove the rear roadwheels. 2Undo the two bolts securing the caliper shield in position and remove the shield from the rear of the caliper. 3Remove both caliper guide pin bolts whilst,if necessary, using a slim open-ended spanner to prevent the guide pins from rotating. Lift the caliper away from the disc, noting the upper pad spring which is fitted to the roof of the caliper. Tie the caliper to the suspension strut using a piece of wire to avoid straining the hydraulic hose (see illustration). 4Remove the brake pads from the caliper mounting bracket whilst noting the correct fitted positions of the brake pads, pad retainer springs and pad shims. 5Inspect the pads as described for the front brake pads and, if necessary, renew as a complete axle set. Fitting 6Fit the pad retainer springs to the caliper mounting bracket. 7Apply a thin smear of Molykote M77 compound to the sides and back of each pad’s metal backing and to those surfaces of the caliper body and mounting bracket which bear on the pads. In the absence of the specified lubricant, a good quality high- temperature brake grease (silicone- or PBC/Poly Butyl Cuprysil-based) or anti-seize compound (eg Holts Copaslip) may be used. Fit the shims to the back of both pads, noting that the smaller shim must be fitted to the piston side pad, and apply a thin smear of lubricant to the back of each shim. Do not allow lubricant to foul the friction material. 8Install the brake pads in the caliper mounting bracket, ensuring that the friction material is against the disc and the pad with the smaller shim attached is fitted on the inside. 9If new pads have been fitted, it will be necessary to retract the piston fully into the caliper bore by rotating it in a clockwise direction. This can be achieved by using a suitable pair of circlip pliers as a peg spanner or by fabricating a peg spanner for the task. Provided that the master cylinder reservoir has not been overfilled with hydraulic fluid, there should be no spillage, but keep a careful watch on the fluid level while retracting the piston. If the fluid level rises above the MAX level line at any time, the surplus should be syphoned off or ejected via a plastic tube connected to the bleed screw. 10Ensure the upper pad spring is still in position in the caliper then slide the caliper into position in its mounting bracket. When fitting the caliper, ensure that the lug on the rear of the piston side pad is located in one of the piston slots. Refit the caliper guide pin bolts and tighten them to the specified torque setting. 11Depress the footbrake to bring the piston into contact with the pads then check that the lug on the piston side pad is located in one of the piston slots. If necessary, remove the caliper and adjust the piston position as described above. Refit the shield to the rear of the caliper. 12Repeat the above procedure on the remaining rear brake caliper. 9•14 Braking system 18.3 Wheel cylinder retaining bolts (A) and brake pipe union nut (B) 1689 Rover 214 & 414 Updated Version 09/97
13Once both calipers have been done, repeatedly depress the brake pedal until normal (non-assisted) pedal operation returns, then repeatedly apply the handbrake to set handbrake adjustment. Check the operation of the handbrake and, if necessary, adjust the cable as described in Chapter 1. 14Refit the roadwheels, then lower the vehicle to the ground and tighten the roadwheel nuts to the specified torque. 15Check the hydraulic fluid level.21 Rear brake caliper- removal, overhaul and refitting 4 Removal 1Chock the front wheels, then jack up the rear of the vehicle and support on axle stands. Remove the rear wheel. 2Undo the two bolts securing the calipershield in position and remove the shield from the rear of the caliper. 3Extract the spring clip and clevis pin securing the handbrake cable to the caliper handbrake lever, then remove the clip securing the outer cable to its mounting bracket and detach the handbrake cable from the caliper. 4Minimise fluid loss by removing the master cylinder reservoir cap and then tightening it down onto a piece of polythene to obtain an airtight seal (taking care not to damage the sender unit), or by using a brake hose clamp, a G-clamp or a similar tool to clamp the flexible hose. 5Clean the area around the hose union, then undo the brake hose union bolt and disconnect the hose from the caliper. Plug the end of the hose and the caliper orifice to prevent dirt entering the hydraulic system. Discard the sealing washers as they must be renewed whenever disturbed. 6Remove both the caliper guide pin bolts whilst, if necessary, using a slim open-ended spanner to prevent the guide pins from rotating, then lift the caliper away from the disc, noting the upper pad spring which is fitted to the roof of the caliper. Note that the brake pads need not be disturbed and can be left in position in the caliper mounting bracket. Overhaul 7With the caliper on the bench, wipe away all traces of dust and dirt. Avoid inhaling the dust as it is injurious to health. 8Using a small screwdriver, carefully prise out the dust seal from the caliper bore. 9Remove the piston from the caliper bore by rotating it in an anti-clockwise direction. This can be achieved using a suitable pair of circlip pliers as a peg spanner or by fabricating a peg spanner for the task. Once the piston turns freely but does not come out any further, then it can be withdrawn by hand, or if necessary, pushed out by applying compressed air to the union bolt hole. Only low pressure should be required such as is generated by a foot pump. 10With the piston removed, extract the circlip from inside the piston and withdraw the thrustwasher, spring and adjuster nut. 11Remove the piston (fluid) seal whilst taking great care not to scratch the caliper bore. 12Extract the circlip from the caliper bore and withdraw the spring cover, spring, spring seat, bearing and adjusting bolt. Then remove the adjusting bolt piston, noting the O-ring fitted to the rear of the piston, and withdraw the small pushrod. 13Slacken and remove the handbrake lever retaining nut and washer and remove the return spring, lever and dust seal. Withdraw the handbrake mechanism cam from the caliper and remove the cam washer. 14Withdraw the guide pins from the caliper mounting bracket and remove the guide pin gaiters.

15Inspect all the caliper components as described for the front brake caliper and renew as necessary. 16On reassembly ensure that all components are absolutely clean and dry. 17Apply a good quality high-temperature brake grease (silicone- or PBC/Poly Butyl Cuprysil-based) or anti-seize compound (eg Holts Copaslip) to the handbrake mechanism cam and refit the cam washer and cam to the caliper. Fit the dust seal, lever, return spring and washer and tighten the handbrake lever retaining nut securely. 18Fit a new O-ring to the adjusting bolt piston then insert the small pushrod into the rear of the piston and install the adjusting bolt piston assembly in the caliper bore. Operate the handbrake lever and check that the piston is free to move smoothly then refit the adjusting bolt, followed by the bearing and spring seat. Fit the spring, so that its tapered end is innermost, then install the spring cover. Secure all the above components in position with the circlip, ensuring that it is correctly seated in the groove in the caliper bore. 19Locate the adjusting nut with the cutout on the inside of the caliper piston and refit the spring, thrustwasher and circlip. Ensure the circlip is correctly located in its groove. 20Soak the piston and the new piston (fluid) seal in clean hydraulic fluid. Smear clean fluid on the cylinder bore surface. 21Fit the new piston (fluid) seal using only the fingers to manipulate it into the cylinder bore groove and refit the piston assembly. Turn the piston in a clockwise direction, using the method employed on dismantling, until it is fully retracted into the caliper bore. 22Fit the dust seal to the caliper ensuring that it is correctly located in the caliper and also the groove on the piston. 23Apply the grease supplied in the repair kit, or a good quality high-temperature brake grease (silicone- or PBC/Poly Butyl Cuprysil- based) or anti-seize compound (eg Holts Copaslip), to the guide pins and fit the new gaiters. Fit the guide pins to the caliper mounting bracket, ensuring that the gaiters are correctly located in the grooves on both the guide pin and mounting bracket. Refitting 24Ensure the upper pad spring is still in position in the caliper then slide the caliper into position in its mounting bracket. When fitting the caliper, ensure that the lug on the rear of the piston side pad is located in the centre of the caliper piston at the point where the two piston slots cross. Refit the caliper guide pin bolts and tighten them to the specified torque setting. 25Position a new sealing washer on each side of the hose union and refit the brake hose union bolt. Ensure that the brake hose union is correctly positioned between the lugs on the caliper then tighten the union bolt to the specified torque setting. 26Remove the brake hose clamp, wherefitted, and bleed the hydraulic system. Providing the precautions described were taken to minimise brake fluid loss, it should only be necessary to bleed the relevant rear brake. 27Refit the handbrake cable outer to its mounting bracket and secure it in position with the retaining clip. Ensure the return spring is located in the groove in the operating lever then refit the handbrake cable to lever clevis pin and secure it in position with the spring clip. 28Depress the brake pedal several times until normal (non-assisted) operation returns then check and, if necessary, adjust the handbrake cable as described in Chapter 1. 29Refit the shield to the rear of the caliper and tighten its retaining bolts securely. 30Refit the roadwheel, then lower the vehicle to the ground and tighten the roadwheel nuts to the specified torque. 31Check the hydraulic fluid level. 22 Rear brake disc- inspection, removal and refitting 3 Note:If either rear brake disc requires renewal, both should be renewed at the same time to ensure even and consistent braking. Inspection 1Chock the front wheels, then jack up the rear of the vehicle and support on axle stands. Remove the appropriate rear roadwheel. 2Inspect the disc as described for the front brake disc. Removal 3Undo the two caliper shield retaining bolts and remove the shield from the rear of the caliper. 4Undo the two bolts securing the caliper mounting bracket to the trailing arm assembly and slide the caliper assembly off the disc. Using a piece of wire or string, tie the caliper to the rear suspension coil spring to avoid placing any strain on the hydraulic brake hose. 5Use chalk or paint to mark the relationship of the disc to the hub, then remove the two screws securing the brake disc to the hub and remove the disc. If the disc is a tight fit on the hub, it can be drawn off by screwing two bolts into the jacking holes provided. Refitting 6Refitting is the reverse of the removal procedure, noting the following: a) Ensure that the mating surfaces of the disc and hub are clean and flat. b) Align (if applicable) the marks made on removal. c) If a new disc has been fitted, use a suitable solvent to wipe any preservative coating from the disc before refitting the caliper.d) Tighten the disc retaining screws, caliper bracket bolts and roadwheel nuts to their specified torque wrench settings. 23 Handbrake lever- removal and refitting 2 Removal 1With the vehicle parked on level ground, chock the roadwheels so that the vehicle cannot move. 2From inside the vehicle, prise out the cover from the top of the rear centre console section to gain access to the two retaining screws. Undo the two screws and remove the rear console section. 3Remove the handbrake lever rubber gaiter and disconnect the wiring connector from the lever warning lamp switch (see illustration). 4Slacken and remove the handbrake cable adjusting nut from the rear of the lever and undo the bolts securing the handbrake lever assembly to the floorpan (see illustration opposite). 5Lift the handbrake assembly out of position, noting the spring which is fitted to the lever adjusting rod. Refitting 6Refitting is a reverse of the removal procedure. Prior to refitting the handbrake lever rubber gaiter, adjust the handbrake cable as described in Chapter 1. 24 Handbrake cables- removal and refitting 2 Removal 1Firmly chock the front wheels then jack up the rear of the vehicle and support it on axle stands. The handbrake cable consists of two sections (right and left-hand), which are linked to the lever assembly by an equalizer plate. Each section can be removed individually. 9•16 Braking system 23.3 Handbrake lever switch (A), mounting bolts (B) and adjusting nut (C) 1689 Rover 214 & 414 Updated Version 09/97

Undo the two screws and remove the rear console section. 3Slacken and remove the handbrake cable adjusting nut from the rear of the lever and disconnect the equalizer plate, noting the spring which is fitted to the lever adjusting rod. 4Undo the two bolts securing the cable outer retaining plate to the floor pan (see illustration). Remove the retaining plate then detach the relevant cable inner from the equalizer plate and release the cable grommet from the floorpan. 5On models equipped with ABS, working from underneath the vehicle, remove the two brake caliper shield retaining bolts and remove the shield from the caliper. Extract thespring clip and clevis pin securing the handbrake cable to the caliper handbrake lever then remove the clip securing the cable outer to its mounting bracket and detach the handbrake cable from the caliper. 6On non-ABS models, remove the relevant rear brake drum. Remove the trailing shoe retainer spring and pin, using a pair of pliers to press in the retainer clip until it can be rotated through 90º and released. Ease the trailing shoe out of the lower pivot point to release the tension of the return spring, then disconnect the lower return spring from both shoes. Disconnect the handbrake cable from the trailing shoe then use a 12 mm spanner to compress the handbrake cable retaining tangs and withdraw the cable from the rear of the backplate (see illustration). 7On all models, release the main silencer from its three rubber mountings and carefullylower the tailpipe section to gain access to the heat shield. Undo the three heat shield retaining bolts and remove the shield from the vehicle underbody. 8Work along the length of the cable section and remove all bolts securing the cable outer to the vehicle underbody and trailing arm. Once free, withdraw the cable from underneath the vehicle and, if necessary, repeat the procedure for the remaining cable section. Refitting 9Refitting is a reversal of the removal sequence noting the following: a) Lubricate all exposed linkages and cable pivots with a good quality multi-purpose grease. b) Ensure the cable outer grommet is correctly located in the floorpan and that all retaining bolts are tightened to the specified torque. c) On non-ABS models, relocate the trailing shoe and refit the brake drum. d) Prior to refitting the rear centre console section, adjust the handbrake cable as described in Chapter 1. 25 Stop lamp switch- removal, refitting and adjustment 2 Removal 1Working inside the vehicle, undo the five screws and remove the right-hand lower facia panel. 2Disconnect the wiring connector from the stop lamp switch (see illustration). 3Slacken the stop lamp switch locknut and unscrew the switch from its mounting bracket.

Place a piece of polythene over the filler neck and securely refit the cap (taking care not to damage the sender unit). This will minimise brake fluid loss during subsequent operations. As an added precaution, place absorbent rags beneath the modulator brake pipe unions. 4Wipe clean the area around the brake pipe unions then make a note of how the pipes are arranged for reference when refitting. Unscrew the union nuts and carefully withdraw the pipes. Plug or tape over the pipe ends and valve orifices to minimise the loss ofbrake fluid and to prevent the entry of dirt into the system. Wash off any spilt fluid immediately with cold water. 5Undo the earth lead retaining nut and slacken the modulator block mounting nuts. Disconnect the earth lead and remove the modulator assembly from the engine compartment. Do not attempt to dismantle the modulator block assembly. Overhaul of the unit is a complex job and should be entrusted to a Rover dealer. Refitting 6Refitting is the reverse of the removal procedure, noting the following: a) Tighten the modulator block mounting nuts to the specified torque. b) Refit the brake pipes to their respective unions and tighten the union nuts to the specified torque. c) On completion, bleed the braking system.

Refitting 11Refitting is the reverse of the removal procedure, noting the following: a) Ensure that the sensor and hub sealing faces are clean then refit the sensor and tighten its retaining bolts to the specified torque. b) Ensure the sensor wiring is correctly routed and all bracket retaining bolts are tightened to the specified torque. Rear wheel sensor Removal 12Chock the front wheels then jack up the rear of the vehicle and support it on axle stands. Remove the appropriate roadwheel. 13Trace the wiring back from the sensor to the wiring connector then free the connector from its retaining clips and disconnect it. 14Undo the sensor lead bracket retaining bolts and remove the brackets. 15Slacken and remove the bolt securing the strap to the sensor cover then undo the sensor cover retaining bolts and remove the cover. 16Undo the two bolts securing the sensor to the rear hub assembly and remove it from the vehicle, along with the shim which is fitted behind it. Refitting 17Refitting is the reverse of the removal procedure, noting the following: a) Ensure the sensor and hub sealing faces are clean, then install the sensor and shim and tighten the sensor retaining bolts to the specified torque. b) Refit the sensor cover, cover strap retaining bolt and sensor lead brackets, then tighten all retaining bolts to the specified torque. c) Reconnect the sensor lead wiring connector and refit the connector to its retaining clip. Reluctor rings 18The reluctor rings are not available as separate items. The front rings are available only as an integral part of the outer constant velocity joint assembly and the rear rings are available only as an integral part of the rear hub. 19The front reluctor rings are situated on the outer constant velocity joint and the rear reluctor rings are part of the stub axle assembly. Examine the rings for signs of damage such as chipped or missing teeth and renew as necessary. Relays 20Both the solenoid relay and return pump relay are located in the modulator block assembly. To gain access to them, undo the relay cover retaining screw and lift off the cover. Either relay can then be simply pulled out of position.
