REMOVAL & INSTALLATION
- If equipped with an air bag, disconnect the negative battery cable and properly disable the Supplemental Restraint System (SRS), as detailed in Chassis Electrical .
- Loosen the lug nuts, then Raise and safely support the vehicle on jackstands.
- Remove the wheels.
- Remove the banjo bolt and disconnect the brake hose from the caliper. Plug the hose immediately.
- Remove the mounting bolt(s) and the caliper.
- Position the caliper on the vehicle. Use new gaskets on the banjo bolt and tighten to 25 ft. lbs. (35 Nm).
- Install the mounting bolt(s). On vehicles that have long pins below the threads of the caliper bolt, tighten the bolt to 54 ft. lbs. (75 Nm). Vehicles with short bolts and no pin beyond the threads should be tightened to 33 ft. lbs. (45 Nm).
- Bleed the brakes.
- If equipped, enable the SRS system and connect the negative battery cable.
See Figures 1, 2, 3, 4 and 5
- Remove the caliper from the vehicle and drain the remaining brake fluid from it.
- Remove the piston from the caliper. Resist the temptation to grab it with pliers; you'll score the metal. Follow this procedure instead:
- Remove the piston, boot and seal.
- Clean the piston and bore with clean brake fluid. Inspect the surfaces very carefully; they must be virtually perfect. Any scoring or rust is grounds for replacement. Very light surface rust may be removed with fine crocus cloth wet with brake fluid, but any pitting requires replacement.
- Install a new piston seal into the groove of the cylinder lubricated with brake fluid.
- Install the boot on the piston.
- Lubricate the caliper bore and piston with clean brake fluid. Install the piston into the cylinder bore, solid end in first.
- Make certain the piston boot is fitted into the lip around the caliper bore. Push the piston all the way in so the caliper will reinstall over the brake pads easily.
- Reinstall the caliper. Fill the reservoir as needed and bleed the brake system.
