should be approximately 4 mm to 6 mm (0.16
to 0.25 in). If adjustment is necessary;
·Turn the starter switch to position 0 and
disconnect the battery negative lead.

154 BRAKE PAD, DISC AND CALIPER CHECK
If the vehicle is being operated in arduous
conditions, especially when deep mud and/or
wading situations are regularly encountered,
the condition of the brake pads, discs and
calipers should be checked at least weekly, if
not even more frequently.
Hydraulic disc brakes are fitted to the front
and rear wheels, they are self adjusting and
therefore, no provision for manual adjustment
is made.
·Check the thickness of the brake pads,
which should not be less than 3mm
(0.125 in).
·Check for uneven brake pad wear.
·Check for oil contamination on the brake
discs and pads.
·Check condition of the brake discs for
wear and/or corrosion.
·Check the brake calipers for any leaking
brake fluid.
If necessary, any replacement or rectification
of discs, brakes or calipers, should be carried
out by a Land Rover dealer.

155 HANDBRAKE CHECK/ADJUSTMENT
WARNING
For safety, DO NOT work underneath the
vehicle unless it is safely parked with the
wheels chocked, or is supported by heavy
duty stands.
Ensure the vehicle is parked on firm, level
ground and chock the wheels.
If the parking brake movement is excessive,
adjust as follows:
·Raise one rear wheel clear of the ground
and ensure it is supported securely with
an axle stand.
·Release the handbrake.
·Tighten the adjusting bolt (3) until brake
drum will not rotate (by hand).
·Further tighten the adjusting bolt to a
torque of 25 Nm (18 lbf/ft) to ensure that
the brake drum is locked - if this is not the
case, consult a Land Rover dealer.
·Finally, slacken the adjusting bolt by
turning it 1.5 turns anti-clockwise.
The brake drum should now be free to rotate,
and the brakes shoes correctly adjusted.
PROPELLER SHAFT LUBRICATION
