Replacement

REMOVAL PROCEDURE
1. Remove two-thirds of the brake fluid from the master cylinder reservoirs.
2. Raise the vehicle and support.
3. Remove the tire and wheel assembly.





4. Depress the piston into the brake caliper housing bore to provide clearance between the brake pads and the brake rotor.
5. Make sure one end of the C-clamp or equivalent, rests on the inlet fitting bolt and the other end against the outboard brake pad.





6. Remove the brake caliper guide pin bolts.
7. Remove the brake caliper from the brake caliper mounting bracket and the brake rotor.
8. Remove the brake pads.

INSTALLATION PROCEDURE
1. Install new brake pads on the brake caliper mounting bracket.
a. The outboard brake pad with insulator installed toward the brake caliper housing.
b. The inboard brake pad with the wear sensor installed nearest the brake caliper piston.
c. The wear sensor must be in the trailing position during forward wheel rotation.
d. Replace brake pads in axle sets only.
2. Install the brake caliper to the brake caliper mounting bracket and the brake rotor.
3. Install the brake caliper guide pin bolts.
- Tighten the brake caliper guide pin bolts to 31 Nm (23 ft. lbs.).

CAUTION: 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 system.

4. Install the tire and wheel assembly.
- Tighten the wheel nuts in sequence to 140 Nm (100 ft. lbs.).
5. Lower the vehicle.
6. Refill the master cylinder to the proper level with clean, fresh brake fluid. Refer to Master Cylinder Description in Hydraulic Brakes.
7. With the engine running, pump the brake pedal slowly and firmly to seat the brake pads.
8. Inspect the hydraulic brake system for brake fluid leaks.
9. Burnish brakes as necessary.
