Rear Brake Caliper Replacement

Callout	Component Name
CAUTION: Refer to Brake Fluid Irritant Caution . CAUTION: Refer to Brake Dust Caution . IMPORTANT: New brake calipers are packaged filled with brake fluid. DO NOT drain the brake fluid from the new caliper prior to installation. Draining the brake fluid from the new brake caliper will prevent the brake caliper from bleeding properly. Preliminary Procedures Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle . Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation . Release the tension from the park brake cables. Refer to Park Brake Adjustment . Disconnect the park brake cable from the actuator lever on the brake caliper.
1	Brake Hose Fitting Bolt NOTE: Refer to Fastener Notice . Tip: If installing a new brake caliper, hand install the brake hose fitting bolt, the new gaskets and the hose to the new caliper with the caliper inverted to prevent brake fluid loss. Tighten: 40 N.m (20 lb ft)
2	Brake Hose Fitting Gasket (Qty: 2) Tip: DO NOT reuse the brake hose fitting gaskets. Install NEW gaskets.
3	Brake Hose Tip: Plug the brake caliper inlet port to prevent brake fluid loss and contamination. Plug the brake hose fitting to prevent brake fluid loss and contamination.
4	Brake Caliper Guide Pin Seal (Qty: 2)
5	Brake Caliper Guide Pin (Qty: 2) Tighten: 27 N.m (20 lb ft)
6	Brake Caliper Guide Pin Bushing (Qty: 2)
7	Brake Caliper NOTE: When using a large C-clamp to compress a caliper piston into a caliper bore of a caliper equipped with an integral park brake mechanism, do not exceed more than 1 mm (0.039 in) of piston travel. Exceeding this amount of piston travel will cause damage to the internal adjusting mechanism and/or the integral park brake mechanism. Procedure Use a large C-clamp to compress the brake caliper piston slightly to ease caliper removal. DO NOT exceed 1 mm (0.039 in) of caliper piston travel. Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding (Manual) or Hydraulic Brake System Bleeding (Pressure) . 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 piston and brake pads. Fill the master cylinder reservoir. Refer to Master Cylinder Reservoir Filling . Connect the park brake cable to the actuator lever on the caliper. Adjust the tension of the park brake cables. Refer to Park Brake Adjustment . Burnish the brake pads and rotors. Refer to Brake Pad and Rotor Burnishing .
