Rear Disc Brake Pads Replacement (JH5, JH6)
Removal Procedure
Warning: Refer to Brake Dust Warning Brake Dust Warning.
Note: Always replace disc brake pads in axle sets.
1. Inspect the fluid level in the brake master cylinder reservoir.
2. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding.
3. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.
4. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle Service and Repair.
5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation Service and Repair.
6. Inspect the caliper operation. Refer to Brake Caliper Inspection Testing and Inspection.
7. Place a C-clamp as shown. Slowly bottom the pistons of the caliper. It may be necessary to reposition the C-clamp to allow both of the pistons to bottom into the caliper bores.
Caution:
Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
8. Remove the caliper from the mounting bracket and support the caliper with heavy mechanic's wire or equivalent. DO NOT disconnect the hydraulic brake flexible hose from the caliper. Refer to Rear Brake Caliper Replacement (JH5, JH6) Rear Brake Caliper Replacement (JH5, JH6)Rear Brake Caliper Replacement (JH9) Rear Brake Caliper Replacement (JH9).
9. Inspect the caliper assembly. Refer to Brake Caliper Inspection Testing and Inspection.
10. Remove the brake pads from the brake caliper bracket. Note the orientation.
11. Remove and discard the anti-rattle clips from the brake caliper mounting bracket.
Installation Procedure
1. Install the anti-rattle clips to the brake caliper bracket.
2. Install the brake caliper. Refer to Rear Brake Caliper Replacement (JH5, JH6) Rear Brake Caliper Replacement (JH5, JH6)Rear Brake Caliper Replacement (JH9) Rear Brake Caliper Replacement (JH9).
3. Install the brake pads to the brake caliper bracket. Place the new pads in the same orientation as noted during removal.
4. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation Service and Repair.
5. Lower the vehicle.
6. With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
7. Slowly release the brake pedal.
8. Wait 15 seconds, then repeat steps 6-7 until a firm pedal is obtained. This will properly seat the brake caliper pistons and brake pads.
9. Fill the master cylinder reservoir to the proper level with clean brake fluid. Refer to Master Cylinder Reservoir Filling Master Cylinder Reservoir Filling.
10. Burnish the brakes pads and rotors as necessary. Refer to Brake Pad and Rotor Burnishing Procedures.
