- Raise and safely support the rear of the vehicle on jackstands and remove the rear wheels.
- With the parking brake handle down and the brake fully released, firmly apply the brake pedal once.
- Pull the parking brake lever up 2-3 clicks. If the rear wheels cannot be turned by hand, no adjustment is required.
- If adjustment is required, loosen the locknuts and the adjusting nuts to just relieve the tension on the cables.
- Hold the release button on the handle and move the handle up and down 3 or more times to seat the cables and make sure they move freely, then leave the handle down.
- Tighten the cable adjusting nuts evenly until the actuating levers on the calipers just move off their stops. The gap must be less than 0.059 inch (1.5mm).
To check for correct adjustment:
- At the first click, the rotors should turn by hand with some drag.
- At the second click, the rotors should be difficult to turn.
- At the third click, it should not be possible to turn the rotors by hand.
- When the brake handle is released, the rotors should turn freely.
Removal & Installation
Some brake pads contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.
- Raise and safely support the vehicle and remove the rear wheels.
- Remove a sufficient quantity of brake fluid from the master cylinder reservoir to prevent it from over flowing when installing the pads. This is necessary as the caliper piston must be forced into the cylinder bore to provide sufficient clearance to install new pads.
- Remove the parking brake cable clip from the caliper. Disconnect the parking brake cable.
- Hold the guide pin with a back-up wrench and remove the upper mounting bolt from the brake caliper.
- Swing the caliper downward and remove the brake pads.
- Check the rotor for scoring and resurface or replace as necessary. Check the caliper for fluid leaks or a damaged dust seal. If any damage is found, the caliper will require overhauling or replacement.
- Retract the piston into the housing by rotating the piston clockwise.
- Carefully clean the anchor plate and install the new brake pads onto the pad carrier.
- Install the caliper to the pad carrier using a new self locking bolt or a thread locking compound and tighten to 26 ft. lbs. (35 Nm).
- Attach the hand brake cable to the caliper. It may be necessary to back off the adjustment nuts at the hand brake handle.
- Fill the reservoir with brake fluid and pump the brake pedal about 40 times with the engine off to set the piston. Setting the piston with the power assist could cause the piston to jam.
- Check the parking brake operation, adjust the cable if necessary.
- Road test the vehicle.
