Caution: Refer to Brake Dust Caution in the Preface section.

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 .
5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation .
6. Inspect the caliper operation. Refer to Brake Caliper 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.




Notice: 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.
9. Inspect the caliper assembly. Refer to Brake Caliper Inspection .



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

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



3. Install the brake caliper to the mounting bracket.
4. Perform the following procedure before installing the caliper guide pin bolts.

4.1.	Remove all traces of the original adhesive patch.

4.2.	Clean the threads of the bolt with brake parts cleaner or the equivalent and allow to dry.

4.3.	Apply Threadlocker GM P/N 12345493 (Canadian P/N 10953488) to the threads of the bolt.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

5. Install the brake caliper guide pin bolts.

Tighten
Tighten the brake caliper guide pin bolts to 108 N·m (80 lb ft).

6. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation .
7. Lower the vehicle.
8. With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
9. Slowly release the brake pedal.
10. Wait 15 seconds, then repeat steps 8-9 until a firm pedal is obtained. This will properly seat the brake caliper pistons and brake pads.
11. Fill the master cylinder reservoir to the proper level with clean brake fluid. Refer to Master Cylinder Reservoir Filling .
12. Burnish the brakes pads and rotors as necessary. Refer to Brake Pad and Rotor Burnishing .
