Brake Caliper Replacement
REMOVAL PROCEDURE1. Remove two-thirds of the brake fluid from the master cylinder.
2. Raise the vehicle.
3. Support the vehicle with safety stands.
4. Remove the tire and wheel assembly.
5. Position a C-clamp around the outer pad and the caliper. Tighten the clamp until the piston bottoms in its bore.
6. Remove the C-clamp.
7. Remove the brake hose from the caliper.
8. Remove the mounting bolts.
9. Remove the caliper assembly.
10. Remove the bushings.
11. Remove the sleeves (RWD only).
12. Replace any corroded bolts or sleeves. Do not attempt to polish away any corrosion.
INSTALLATION PROCEDURE
1. Lubricate the sleeves and the bushings with Delco Silicone Lube GM PIN 18010909 or the equivalent.
2. Install the bushings.
3. Install the sleeves (RWD).
4. Install the caliper assembly.
NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.
5. Install the mounting bolts.
^ Tighten the bolts to 51 Nm (38 ft. lbs.).
6. Install the brake hose to the caliper.
^ Tighten the bolts to 44 Nm (32 ft. lbs.).
7. Measure the clearance between the caliper and the steering knuckle.
^ Measure the clearance at each end of the caliper individually and then add the measurements together.
^ The total should be 0.26 - 0.60 mm (0.010 - 0.024 inch) on RWD models.
^ The total should be 0.13 - 0.30 mm (0.005 - 0.012 inch) on F4WD models.
8. Install the tire and wheel.
9. Remove the safety stands.
10. Lower the vehicle.
Important: Pump the brake pedal until it is firm before moving the vehicle. Check the brake fluid level in the master cylinder after pumping the brakes. If necessary, fill the reservoir to the proper level.
