Installation Procedure
- Lubricate all rubber parts with clean brake fluid.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.
- Install the bleeder valve to the caliper.
Tighten
Tighten the bleeder valve to 8.3 N.m (74 lb in).
- Lubricate the 2 new dust boots (2) with Lubriplate® Lubricant, GM P/N 12346293, or an equivalent lubricant meeting the requirements of NLGI #2 Category LB or GC-LB.
- Install the 2 new dust boots (2) onto the caliper carrier (1). Use a wrench and a hammer in order to tap the dust boots onto the caliper carrier. Verify that the metal plate portion of the dust boot fits snugly in the torque plate.
- Lubricate the 2 sliding pins with Lubriplate® Lubricant, GM P/N 12346293, or an equivalent lubricant meeting the requirements of NLGI #2 Category LB or GC- LB.
- Insert the sliding pin with the sliding bushing into the lower portion of the torque plate.
- Insert the sliding pin without the sliding bushing into the upper portion of the torque plate.
- Lubricate the following components with Lubriplate® Lubricant, GM P/N 12346293, or an equivalent lubricant meeting the requirements of NLGI #2 Category LB or GC-LB:
- The piston
- The seal
- The cylinder boot
- Install the piston seal and piston into the caliper housing.
- Install the piston boot and caliper set ring into the caliper housing.
Important: Ensure that the dust boots are secured firmly into each caliper groove.
- Install the caliper to the vehicle. Refer to Brake Caliper Replacement .
