Caution: Refer to Brake Dust Caution in Cautions and Notices.

Removal Procedure






1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
3. Install a C-clamp over the body of the brake caliper, with the C-clamp ends against the rear of the caliper body and the outboard disc brake pad.
4. Slowly tighten the C-clamp until the pistons are pushed into the caliper bores enough to remove the caliper from the pads.
5. Remove the C-clamp from the caliper.
6. Loosen the rear brake caliper mounting bolts. Do not remove.






7. Remove the brake caliper bracket mounting bolts (2).
8. Remove the brake caliper bracket (1) and brake caliper as an assembly.

Note: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from it's 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.

9. Remove the brake caliper mounting bolts from the brake caliper mounting bracket and support the brake caliper with heavy mechanic's wire or equivalent.






10. Remove the brake pads from the brake caliper mounting bracket.
11. Remove the anti-rattle clips from the brake caliper mounting bracket.

Installation Procedure

1. Install the anti-rattle clips to the brake caliper mounting bracket.
