REMOVAL & INSTALLATION
- Remove 1 / 2 of the brake fluid from the master cylinder reservoir.
- Raise and safely support the vehicle.
- Remove the wheel and tire assembly.
- Reinstall two wheel nuts in order to retain the rotor to the hub and bearing assembly.
- Install a large C-clamp over the top of the caliper housing and against the back of the outboard pad.
- Slowly tighten the C-clamp until the piston is pushed into the caliper bore.
- If the caliper is to be completely removed from the vehicle for bench service, disconnect and cap the brake line from the caliper. Discard the old washers.
- Plug the exposed brake line fitting and caliper housing fitting to in order to prevent fluid loss and contamination.
- Brace the sleeves with a wrench and remove the guide pin bolts.
- Lift the caliper off of the caliper bracket.
- If overhauling the caliper, remove it completely from the vehicle and follow procedures as outlined in the section under brake caliper overhaul.
- Liberally coat the inside diameter of the mounting guide sleeve bores using silicone grease.
- Install the caliper, over the rotor and pads, onto the caliper bracket.
- Install the mounting guide pin bolts and sleeve assemblies. Tighten the mounting bolt to 23 ft. lbs. (31 Nm).
- Install the brake line to the caliper. Make sure washers are on both sides of the brake hose fitting. Tighten to 37 ft. lbs. (50 Nm).
- Bleed the system as outlined in this section under Brake System Bleeding.
- Remove the two wheel nuts previously installed.
- Reinstall the wheel and tire assembly. Torque the lug nuts to 100 ft. lbs. (140 Nm).
- Lower the vehicle.
- Pump the brake pedal several times to achieve a firm pedal before attempting to move the vehicle.
- Check the brake fluid level in the master cylinder fluid reservoir and add fluid as necessary.
- Road test the vehicle and check for proper brake system operation.
- Remove the caliper from the vehicle and place on a clean workbench.
The first method is as follows:
- Stuff a shop towel or a block of wood into the caliper to catch the piston.
- Remove the caliper piston using compressed air applied into the caliper inlet hole. Inspect the piston for scoring, nicks, corrosion and/or worn or damaged chrome plating. The piston must be replaced if any of these conditions are found.
- For the second method, you must rotate the piston to retract it from the caliper.
- If equipped, remove the anti-rattle clip.
- Use a prytool to remove the caliper boot, being careful not to scratch the housing bore.
- Remove the piston seals from the groove in the caliper bore.
- Carefully loosen the brake bleeder valve cap and valve from the caliper housing.
- Inspect the caliper bores, pistons and mounting threads for scoring or excessive wear.
- Use crocus cloth to polish out light corrosion from the piston and bore.
- Clean all parts with denatured alcohol and dry with compressed air.
- Lubricate and install the bleeder valve and cap.
- Install the new seals into the caliper bore grooves, making sure they are not twisted.
- Lubricate the piston bore.
- Install the pistons and boots into the bores of the calipers and push to the bottom of the bores.
- Use a suitable driving tool to seat the boots in the housing.
- Install the caliper to the caliper bracket.
- Install the wheel and tire assembly, then carefully lower the vehicle.
- Properly bleed the brake system.
