Removal Procedure
Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.
- Raise the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Hand tighten 2 wheel lug nuts to retain the rotor to the hub.
- Push the piston into the caliper bore in
order to provide clearance between the linings and the rotor:
4.1. | Install a large C-clamp over the top of the caliper housing and against
the back of the outboard pad. |
4.2. | Slowly tighten the C-clamp until the piston is pushed into the caliper
bore far enough to slide the caliper assembly off the rotor. |
- Remove the brake hose bolt (1) Dicard the gaskets (3).
- Plug the caliper housing and brake hose in order to prevent fluid loss
and contamination.
- Remove the caliper bolts (2).
- Remove the caliper from the rotor and the caliper bracket (3).
Installation Procedure
- Lubricate the caliper bolts with GM P/N 18010908 high temperature
silicone brake lubricant or equivalent. Do not lubricate the threads.
- Install the caliper (3) to the caliper
bracket (1) .
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.
- Install the caliper mounting bolts (2) to the caliper bracket (1).
Tighten
Tighten the 2 caliper mounting bolts to 31 N·m (23 lb ft).
- Install the brake hose bolt (1) with new gaskets (3) to the brake
hose inlet fitting (2).
- Install the brake hose with the brake hose bolt (1) to the brake
caliper.
Tighten
Tighten the inlet fitting bolt to 50 N·m (37 lb ft).
- Remove the 2 hand tightened wheel lug nuts retaining the rotor to the
hub.
- Install the wheel and tire assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle.
- Fill the master cylinder to the proper level with clean brake fluid.
Refer to
Master Cylinder Reservoir Filling
.
- Bleed the entire brake system. Refer to
Hydraulic Brake System Bleeding
.
- Inspect the hydraulic brake system for leaks.
