Installation (Front)
NOTE:
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.
- Clean and visually inspect threads of the caliper bracket bolts (2) and mounting holes in the knuckle.
- Apply Threadlocker 272 (GM P/N 12345493) or equivalent to the threads of the brake caliper bracket bolts (2).
- Install the caliper bracket (1) with the bracket bolts (2). See Figure. Tighten the caliper bracket bolts. See TORQUE SPECIFICATIONS .
- Install the front brake pads.
- Install the caliper. See BRAKE CALIPERS .
NOTE:
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.
