REMOVAL & INSTALLATION
See Figures 1 and 2
- To avoid fluid overflow when the caliper piston is pressed into the caliper cylinder bores, remove or siphon part of the brake fluid out of the master cylinder reservoir (connected to the front disc brakes). Discard the removed fluid.
- Loosen the wheel lug nuts then raise and safely support the rear of the vehicle.
- Remove the wheel.
- Place an 8 in. (203mm) C-clamp on the caliper and tighten the clamp to bottom the caliper pistons in their bores. Remove the clamp.
- Remove the two caliper slide pin bolts.
Use care to retain as much of the original caliper slide pin grease as possible.
- Work the rear brake caliper off of the brake pads and adapter mount.
- Position the caliper on a frame member or suspend it with some wire. Do not allow the caliper to hang by the brake hose.
- Remove and discard the pad slippers.
- Remove the outboard brake pad by pressing it in enough to release the locating lug at one end then swing it up to release the other end.
- Remove the inboard brake pad by tilting it enough to release the retainer spring from the caliper piston.
- Inspect the rear brake caliper for damage and wear. Replace as necessary.
- Position the inboard brake pad in the caliper and press the retainer spring fully into the caliper piston.
- Start one end of the outboard pad on the brake caliper and rotate it down until the locating lugs and the retainer spring are fully seated.
- Install new shoe slippers to the caliper mount.
- Position the brake caliper over the rotor and align the sliding pin mounts.
- Install the caliper bolts and tighten them to 20 ft. lbs. (27 Nm).
- Install the wheel and snug the lug nuts.
- Lower the vehicle and tighten the lug nuts to 100 ft. lbs. (135 Nm).
- Check the brake fluid level in the master cylinder reservoir and correct as necessary.
The first couple of times you apply the brakes, the pedal may go to the floor. Continue to pump the brake pedal until it feels firm.
- Start the engine and apply the brakes several times to readjust the caliper pistons. Ensure that the pedal feels firm before operating the vehicle.
- Loosen the wheel lug nuts.
- Raise and safely support the vehicle. Remove the wheel.
- Looking through the rear brake caliper pad inspection hole, measure the pad thickness from the rotor surface to the pads metal backing.
- Minimum pad thickness is 1 / 8 in. (3.12mm), however, your local safety inspection laws may supersede this dimension. Contact the appropriate authorities for specific safety requirements.
- Any pad which is below the minimum allowable thickness will require you to replace all of the pads (both wheels).
