4-38 FRONT AND REAR BRAKESCHAS NOTE: NOTE: WARNING EAS00625 DISASSEMBLING THE FRONT BRAKE CALIPERS The following procedure applies to both of the brake calipers. Before disassembling the brake caliper, drain the brake fluid from the entire brake system. 1. Remove: union bolt 1 copper washers 2 brake hose 3 Put the end of the brake hose into a container and pump out the brake fluid carefully. 2. Remove: brake caliper pistons 1 brake caliper piston seals 2 a. Secure the right side brake caliper pistons with a piece of wood a. b. Blow compressed air into the brake hose joint opening b to force out the left side pis- tons from the brake caliper. Cover the brake caliper piston with a rag. Be careful not the get injured when the pis- tons are expelled from the brake caliper. Never try to pry out the brake caliper pis- tons. c. Remove the brake caliper piston seals.

4-41 FRONT AND REAR BRAKESCHAS WARNING 22 Nm (2.2 mkg, 16 ftlb) 40 Nm (4.0 mkg, 29 ftlb) 30 Nm (3.0 mkg, 22 ftlb) WARNING CAUTION: EAS00638 ASSEMBLING AND INSTALLING THE FRONT BRAKE CALIPERS The following procedure applies to both of the brake calipers. Before installation, all internal brake com- ponents should be cleaned and lubricated with clean or new brake fluid. Never use solvents on internal brake com- ponents as they will cause the piston seals to swell and distort. Whenever a brake caliper is disassembled, replace the brake caliper piston seals. Recommended brake fluid DOT 4 1. Install: brake caliper bracket brake pads brake caliper 1 copper washers New brake hose 2 union bolt 3 Proper brake hose routing is essential to in- sure safe motorcycle operation. Refer to “CABLE ROUTING” in chapter 2. When installing the brake hose onto the brake caliper 1, make sure the brake pipe a touches the projection b on the brake cali- per.
4-42 FRONT AND REAR BRAKESCHAS WARNING CAUTION: 2. Fill: brake master cylinder reservoir (with the specified amount of the recom- mended brake fluid) Recommended brake fluid DOT 4 Use only the designated brake fluid. Other brake fluids may cause the rubber seals to deteriorate, causing leakage and poor brake performance. Refill with the same type of brake fluid that is already in the system. Mixing brake fluids may result in a harmful chemical reaction, leading to poor brake perfor- mance. When refilling, be careful that water does not enter the brake master cylinder reser- voir. Water will significantly lower the boil- ing point of the brake fluid and could cause vapor lock. Brake fluid may damage painted surfaces and plastic parts. Therefore, always clean up any spilt brake fluid immediately. 3. Bleed: brake system Refer to “BLEEDING THE HYDRAULIC BRAKE SYSTEM” in chapter 3. 4. Check: brake fluid level Below the minimum level mark a Add the recommended brake fluid to the proper level. Refer to “CHECKING THE BRAKE FLUID LEVEL” in chapter 3. 5. Check: brake lever operation Soft or spongy feeling Bleed the brake system. Refer to “BLEEDING THE HYDRAULIC BRAKE SYSTEM” in chapter 3.
