REMOVAL & INSTALLATION
See Figures 1, 2 and 3
- Using a clean turkey baster or equivalent, remove about 2 /3 of the brake fluid from the master cylinder.
- Raise and safely support the vehicle.
- Remove the wheel.
Push the piston into the caliper bore to provide clearance between the brake pads and the rotor as follows:
- Install a large C-clamp over the top of the caliper housing and against the back of the outboard pad.
- Slowly tighten the clamp until the piston is pushed into the caliper bore enough slide the caliper off of the rotor.
- Unfasten the banjo bolt attaching the brake hose fitting, then plug the exposed fitting to prevent contamination.
- Unfasten the caliper mounting bolt and sleeve assemblies. Some vehicles have a rubber cap over the bolts, which must be removed first.
- Lift the caliper off of the rotor.
- Inspect the mounting bolts, sleeves and bushings for damage and replace as necessary.
- Liberally coat the inside of the bushings with silicone grease.
- Position the caliper over the rotor into the knuckle, then fasten the mounting bolt and sleeve assemblies. Tighten to 38 ft. lbs. (51 Nm).
- Using new copper washers, install the banjo bolt in the brake hose fitting and attach it to the caliper. Tighten the banjo bolt to 32 ft. lbs. (44 Nm).
- Bleed the brakes as necessary.
- Install the wheel.
See Figures 4 through 10
- Remove the caliper from the vehicle. Place the caliper on a workbench.
- Remove the bushings. Inspect for cuts and nicks. Replace as necessary.
- Stuff a shop towel or a block of wood into the caliper to catch the piston and apply compressed air to the inlet hole.
- Remove and discard the piston boot and seal. Be careful not to scratch the bore. Use of a metal tool is NOT recommended when removing the boot and the seal because of the possibility of scoring and damaging the bore.
- Inspect the piston for scoring, nicks, corrosion and worn chrome plating. Replace as necessary.
- Remove the boot from the caliper housing bolt.
- Remove the bleeder screw and its rubber cap.
- Inspect the housing bore and seal groove for scoring, nicks, corrosion and wear. Crocus cloth can be used to polish out light corrosion.
- Remove the bleeder valve and bleeder valve cap.
- Install the bleeder valve and bleeder valve cap into the caliper.
- Lubricate the piston, caliper and seal with clean brake fluid.
- Install the piston seal into the caliper seal groove. Make sure it is not twisted in the caliper bore groove.
- Bottom the piston into the bore, then secure the boot using J 29077 or an equivalent piston seal installer tool.
- Lubricate the beveled end of the bushings with silicone grease. Pinch the bushing and install the beveled end first. Push the bushing through the housing mounting bore.
- Install the pads into the caliper assembly.
- Install the caliper onto the steering knuckle, then properly bleed the hydraulic brake system.
