WARNING: Refer to Brake Dust Warning . CAUTION: Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak. Preliminary Procedures Inspect the fluid level in the brake master cylinder reservoir. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed before proceeding. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle . Remove the tire and wheel assemblies. Refer to Tire and Wheel Removal and Installation . Compress the brake caliper pistons. Install 2 large C-clamps over the top of the caliper housing and against the back of the outboard brake pad. Slowly and evenly tighten the C-clamps until the caliper pistons are completely retracted into the brake caliper bores. Remove the C-clamps.
1	Brake Caliper Guide Pin Bolt CAUTION: Refer to Fastener Caution . Tighten: 108 N.m (80 lb ft)
2	Brake Caliper Tip: Without disconnecting the brake hose, pivot the brake caliper upward. Support the brake caliper with heavy mechanics wire or equivalent.
3	Disc Brake Pad (Qty: 2) Tip: Note the location of the inner and the outer brake pads for proper installation.
4	Brake Pad Shim (Qty: 2) Tip: If installing new brake pads, DO NOT reuse the shims. Discard the brake pad shims. Thoroughly clean the brake pad hardware mating surfaces of the caliper bracket of any debris and corrosion. After the installation is complete and with the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance. Slowly release the brake pedal. Wait 15 seconds, then repeat steps 3-4 until a firm brake pedal is obtained. This will properly seat the brake caliper pistons and brake pads. Fill the master cylinder to the proper level. Refer to Master Cylinder Reservoir Filling (Non-Hybrid) or Master Cylinder Reservoir Filling (Two-mode Hybrid) . Burnish the brake pads and rotors. Refer to Brake Pad and Rotor Burnishing .
