Disc Brake Hardware Replacement - Rear

Caution: Refer to Brake Dust 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. Remove the brake caliper bolts.





7. Notice: Refer to Brake Caliper Notice in Service Precautions.

Remove the caliper from the caliper bracket. Support the caliper with heavy mechanic's wire or equivalent. DO NOT disconnect the hydraulic brake hose from the caliper.





8. Remove the brake pads from the caliper bracket.
9. Remove the brake pad retainers.





10. Remove the slide pins (5) from caliper bracket (3).
11. Remove the slide pin boots (4) from the caliper bracket.
12. Inspect the disc brake hardware.

Installation Procedure





1. Lubricate the caliper bracket bushings and slide pins with high temperature silicone brake lubricant.
2. Install the slide pin boots (4) to the caliper bracket.
3. Install the slide pins (5) to the caliper bracket (3).





4. 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.





5. 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.





6. Install the brake pad retainers to the caliper bracket.
7. Install the brake pads.





8. Install the brake caliper to the caliper bracket.





9. 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.

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

Install the brake caliper bolts.
^ Tighten the bolts to 42 Nm (31 ft. lbs.).
11. Install the tire and wheel assembly.
12. With the engine OFF, gradually apply the brake pedal approximately 2/3 of its travel distance.
13. Slowly release the brake pedal.
14. Wait 15 seconds, then repeat steps 7-8 until a firm brake pedal is obtained. This will properly seat the caliper pistons and pads.
15. Lower the vehicle.
16. Fill the master cylinder reservoir to the proper level with clean brake fluid, if necessary.
