Brake Caliper Replacement - Rear

Caution: Refer to Brake Dust Caution in Service Precautions.

Caution: Refer to Brake Fluid Irritant Caution in Service Precautions.

Removal Procedure





1. Inspect the fluid level in the brake master cylinder reservoir.
2. If the fluid level is midway between the maximum - full point, and the minimum allowable level, no fluid needs to be removed from the reservoir before proceeding.
3. If the fluid level is higher than midway between the maximum - full point, and the minimum allowable level, remove fluid to the midway point before proceeding.
4. Remove the tire and wheel assembly.
5. Compress the brake caliper piston.
1. Install a C-clamp over the top of the caliper housing and against the back of the outboard pad.
2. Slowly tighten the C-clamp until the pistons are pushed completely into the caliper bores.
3. Remove the C-clamp from the caliper.





6. Clean all dirt and foreign material from the brake hose fitting.

7. Important: Install a rubber cap or plug to the exposed brake pipe fitting end to prevent brake fluid loss and contamination.

Remove the brake hose to caliper bolt.
8. Remove and discard the 2 copper brake hose gaskets. These gaskets may be stuck to the caliper or the brake hose end.
9. Remove the brake hose from the caliper.





10. Remove the brake caliper bolts.





11. Remove the caliper from the caliper bracket.

Installation Procedure





1. Important: Use denatured alcohol to clean the outside surface of caliper boot before installing new brake pads.

If installing NEW brake pads, use a C-clamp (1) in order to compress the piston to the bottom of the caliper bore (3). Use the old brake pad (2), a metal plate or a wooden block across the face of the piston in order to protect the piston and the caliper boot.





2. Important: Use a small flat-bladed tool and lift the inner edge caliper boot next to the piston to release any trapped air.

Ensure that the piston boot is below the level of the piston face.





3. Install the caliper to the caliper bracket.





4. Perform the following procedure before installing the brake caliper bolts.
1. Remove all traces of the original adhesive patch.
2. Clean the threads of the bolt with brake parts cleaner or the equivalent and allow to dry.
3. Apply Threadlocker GM P/N 12345493 (Canadian P/N 10953488) to the threads of the bolt.

5. Notice: Refer to Fastener Notice in Service Precautions.

Install the brake caliper bolts.
^ Tighten the bolts to 42 Nm (31 ft. lbs.).





6. Remove the rubber cap or plug from the exposed brake hose fitting end.

7. Important: Install 2 NEW copper brake hose gaskets.

Assemble the 2 NEW copper brake hose gaskets to the brake hose bolt and brake hose.
8. Install the brake hose to caliper bolt.
^ Tighten the bolt to 40 Nm (30 ft. lbs.).
9. Bleed the hydraulic brake system.
10. Install the tire and wheel assembly.
11. Fill the master cylinder reservoir to the proper level with clean brake fluid, if necessary.
