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.

1. Remove the caliper from the mounting bracket and support the caliper with heavy mechanics wire or equivalent. It is not necessary to disconnect the hydraulic brake flexible hose from the caliper. Refer to Brake Caliper Replacement .
2. Remove the front brake pads.



3. Remove the caliper bracket bolts (2).
4. Remove the caliper bracket (1).

Important: To ensure that the proper clamp load will be present when installed, it is imperative that the threads on the caliper bracket bolts, as well as the mounting holes in the knuckle, be cleaned of all debris and inspected before proceeding with installation.

1. Clean and visually inspect threads of the caliper bracket bolts (2) and mounting holes in the knuckle.
2. Apply THREADLOCKER GM P/N 12345493 (Canadian P/N 10953488) or equivalent to the threads of the brake caliper bracket bolts (2).

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.

3. Install the caliper bracket (1) with the bracket bolts (2).

Tighten
Tighten the caliper bracket bolts to 115 N·m (85 lb ft).

4. Install the front brake pads.
5. Install the caliper. Refer to Brake Caliper Replacement .
