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

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.

Important: The caliper bracket bolt threads and the threaded holes of the caliper bracket must be free of threadlocker residue and debris prior to re-application of threadlocker in order to ensure proper adhesion and fastener retention.

Preliminary Procedures

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
2. Remove the tire and wheel. Refer to Tire and Wheel Removal and Installation .

1

Brake Caliper Bracket Bolt (Qty: 2)

Notice: Refer to Fastener Notice in the Preface section.

1. Prepare the bolts and the threaded holes for assembly.
2. Thoroughly clean the residue from the fastener threads using denatured alcohol or equivalent and allow to dry.
3. Thoroughly clean the residue from the threaded holes using denatured alcohol or equivalent and allow to dry.
4. If reusing the old caliper bracket bolts, apply threadlocker GM P/N 12345493 (Canadian P/N 10953488), or equivalent to 2/3 of the threaded length of the fastener. Ensure that there are no gaps in the threadlocker along the length of the filled area of the fastener.
5. Allow the threadlocker to cure approximately 10 minutes before installation.

Brake Rotor

Procedure

1. If removing the brake rotor to service another component, mark the relationship of the rotor to a wheel stud, before removing the mounting screw.
2. Using the J 42450-A , thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.
3. Using the J 41013 , thoroughly clean any rust or corrosion from the mating surface of the brake rotor.
4. After installing the brake rotor, check the assembled lateral runout (LRO). Refer to Brake Rotor Assembled Lateral Runout Correction .
5. If the assembled lateral runout (LRO) exceeds specifications, refer to Brake Rotor Assembled Lateral Runout Correction - Indexing .
6. If the brake rotor was refinished or replaced, burnish the pads and rotors. Refer to Brake Pad and Rotor Burnishing .
