Important: Refer to Disc Brakes System Description .

1. Remove two-thirds of the brake fluid from the master cylinder reservoir.
2. Raise the vehicle and support the vehicle with proper safety stands. Refer to Lifting and Jacking the Vehicle in General Information.
3. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
4. Position a C-clamp over the outer brake pad and the caliper.

4.1.	Tighten the C-clamp until the piston bottoms in the caliper bore.

4.2.	Remove the C-clamp.




5. Disconnect the brake hose from the caliper.

5.1.	Disconnect the brake hose fitting and two gaskets.

5.2.	Discard the gaskets.

5.3.	Plug the hole in the caliper housing, and in the brake hose fitting.




6. Remove the guide pin bolts.
7. Remove the caliper from the bracket.

1. Inspect the guide pin bolts and sleeves for corrosion.

Replace corroded guide pin bolts and sleeves.




2. Inspect the brake hose fitting bolt. If the through-hole is blocked, remove the blockage or replace the bolt.
3. Inspect the linings for wear. Replace as necessary. Refer to Brake Pad Inspection .
4. Inspect the caliper. Refer to Brake Caliper Inspection .

Caution: Do not move the vehicle until a firm brake pedal is obtained. Failure to obtain a firm pedal before moving vehicle may result in personal injury.

1. Verify that the linings are in place.




Important: Lift the inner edge caliper boot next to the piston. Press out any trapped air. The boot must lay flat below the level of the piston face.

2. Install the caliper over the rotor and into the anchor bracket.
3. Lubricate the guide pin bolts with Delco Silicone Lube (GM P/N 18010909) or equivalent.




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.

4. Install the 2 caliper guide pin bolts to the caliper bracket.

Tighten
Tighten the bolt to 31 N·m (23 lb ft).

Notice: Make sure the brake hose is not twisted or kinked after installation. Damage to the hose could result.




5. Install the brake hose fitting, two new gaskets, and the brake hose fitting bolt.

Tighten
Tighten the brake hose bolt to 54 N·m (40 lb ft).

6. Bleed the caliper. Refer to Hydraulic Brake System Bleeding in Hydraulic Brakes.
7. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
8. Remove the safety stands and lower the vehicle.
9. With the engine running, firmly pump the brake pedal three times.
10. Check the brake system for leaks.
