REMOVAL & INSTALLATION
See Figures 1 through 7
- Raise and safely support the vehicle.
- Remove the wheel and tire assembly.
- Remove the outer disc brake pad spring clip (anti-rattle clip).
- Remove the 2 locator pin covers and remove the locator pins.
- Free the hose from its mounting on the strut.
- Lift the caliper off of the brake rotor.
- Remove the inboard disc brake pad from the caliper.
- If the brake caliper is to be removed from the vehicle, place a pan under the caliper to catch the brake fluid for proper disposal. Disconnect the brake hose at the caliper and allow to drain.
- Remove the brake caliper.
- If the caliper is not to be serviced, tie off the caliper to prevent strain on the brake hose.
- If removed, install the brake hose onto the caliper. Torque the fitting to 10 ft. lbs. (14 Nm).
- Position the inboard disc brake pad into the caliper.
- Make sure that the outboard disc brake pad is positioned properly.
- Reinstall the caliper over the brake rotor and position onto the caliper anchor plate.
- Reinstall the 2 caliper locator pins and torque to 20 ft. lbs. (28 Nm).
- Reinstall the caliper locator pin covers.
- Reinstall the outer disc brake pad spring clip.
- Reconnect the brake hose to the front strut.
- Bleed the brake system of air. Top off the master cylinder when complete.
- If the brake pedal feels spongy, repeat the brake bleeding procedure.
- Reinstall the wheel and tire assembly. Torque the lug nuts to 62 ft. lbs. (85 Nm).
- Lower the vehicle.
- Pump the brake pedal several times to position the brake pads before attempting to move the vehicle.
- Road test the vehicle and check for proper brake system operation.
See Figures 8 through 15
Some vehicles may be equipped dual piston calipers. The procedure to overhaul the caliper is essentially the same with the exception of multiple pistons, O-rings and dust boots.
- Remove the caliper from the vehicle and place on a clean workbench.
Depending upon the vehicle, there are two different ways to remove the piston from the caliper. Refer to the brake pad replacement procedure to make sure you have the correct procedure for your vehicle.
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 in the vehicle.
- Install the wheel and tire assembly, then carefully lower the vehicle.
- Properly bleed the brake system.
