- Loosen the front wheel lugs slightly, then raise the front of the car and safely support it on jackstands.
- Remove the front wheel and tire assemblies.
- The cut out in the top of the front brake caliper allows visual inspection of the disc brake pad. If the lining is worn to within 3mm ( 1 / 8 in.) of the metal disc shoe (check local inspection requirements) replace all four pads (both sides). Minimum pad thickness is 1.0mm (0.039 in.).
- While you are inspecting the brake pads, visually inspect the caliper for hydraulic fluid leaks. If a leak is visible the caliper will have to be rebuilt or replaced.
If a squealing noise occurs from the front brakes while driving, check the pad wear indicator. If there are traces of the indicator contacting the rotor disc, the pads should be replaced.
REMOVAL & INSTALLATION
- Raise and safely support the front of the vehicle.
- Remove the front wheel assembly and temporarily fasten the rotor disc with the hub nuts.
- Remove the sliding main pin from the torque plate. Lift up the brake cylinder and suspend it so the brake hose is not stretched. Do not disconnect the brake hose.
Be sure to do one side at time, in case of running into a state of confusion you can always look at the untouched side to see where you may have made your mistakes.
- Remove the following parts:
- The 2 brake pads.
- The four anti-squeal shims.
- The 2 pad wear indicator plates.
- The 4 pad support plates.
- Install the pad support plates.
- Install a pad wear indicator plate to the pad. Install the 2 anti-squeal shims to each pad.
It is recommended that a suitable anti-squeal compound (available at your local parts house) be applied to both sides of the inner anti-squeal shim.
- Install the 2 pads so that the wear indicator plate is facing upward. Do not allow oil or grease to get in the rubbing face.
- Draw out a small amount of brake fluid from the brake reservoir. Press in the piston with a hammer handle or an equivalent tool.
Always change the pad on one wheel at a time as there is a possibility of the opposite piston flying out.
- Insert the brake cylinder carefully so the boot is not wedged. Install and tighten the sliding main pin. Tighten the pin to 65 ft. lbs. (88 Nm).
When installing the sliding main pin, be careful that the plug installed in the torque plate does not come loose.
- Install the front wheel assemblies and lower the vehicle. Check the fluid level in the master cylinder and add as necessary. Be sure to pump the brake pedal a few times before road testing the vehicle.
- Raise the vehicle and support it safely.
- Remove the wheel and tire assembly.
- When servicing the front pads, loosen the brake caliper upper side mounting bolt. Loosen and remove the lower side mounting bolt. Lift the cylinder and suspend it so the hose is not stretched.
On some models you may be able to place a bolt in the caliper to hold it in the upright position.
- When servicing the rear pads, it will be necessary to remove both upper and lower side caliper mounting bolts. Do not disconnect the brake hose. Remove the anti-squeal springs, brake pads, anti-squeal shims and pad support plates.
- Siphon a small amount of brake fluid from the reservoir. Press in the brake caliper piston with a hammer handle or equivalent.
- Before installing the new pads, check the disc thickness and disc runout.
- Install the pad support plates.
- Install the anti-squeal shims to each pad.
Apply disc brake grease to both side of the inner anti-squeal shims.
- Install the disc pads so the wear indicator plate is facing underneath.
- Install the anti-squeal springs.
- Carefully install the brake caliper so the boot is not wedged. Tighten the caliper mounting bolts to 14 ft. lbs. (20 Nm).
- Install the wheel and tire assembly.
- Check and adjust the fluid level. Apply the brake pedal several times.
- Road test the vehicle for proper operation.
