Loosen the rear wheel lug nuts, raise the vehicle, and support it securely on jackstands before removing the rear wheels. Release the parking brake and remove the discs. Inspect the parking brake surfaces of each disc for wear or damage, replacing them if necessary. If the disc can't be removed when the parking brake is fully released, remove the rubber plug and use a screwdriver to turn the star wheel to retract the parking brake shoes. Clean the assembly with brake system cleaner without using compressed air to blow off brake dust. Remove the upper spring, then take out the adjuster, using pliers to remove the lower spring. Turn the shoe hold-down springs to release them and lift off the shoe, repeating for the remaining shoe. After cleaning the backing plates, apply brake grease to the raised contact surfaces around the perimeter and check the actuator assembly for wear or damage before setting it into place. Install the new parking brake shoes and secure them with their hold-down springs, disassembling the adjuster to clean and lightly lubricate the threads with high-temperature brake grease before placing it between the shoes. Install the top spring to engage the star wheel, attach the lower spring, then reinstall the disc and adjust the shoes. When reinstalling the calipers, ensure the mounting bolts are tightened, and the rest of the replacement procedure follows the reverse of removal. Working through the hole in the center of the
Brake Disc, turn the adjuster star wheel with a screwdriver until the disc is locked, then turn the adjuster star wheel the other way 5 or 6 clicks and verify that the parking brake shoes don't drag by turning the disc. Finally, install the rubber plug in the adjuster hole, noting that the parking brake pedal or lever may need adjustment a few weeks later as the parking brake shoes become seated.
