Release the parking brake. Have an assistant pull the parking brake cable from under the left side of the vehicle until it stops. With the cable under tension from the assistant, insert a 5/32-inch drill bit into the control actuator to lock the assembly into position. Loosen the rear wheel lug nuts. Raise the vehicle and support it securely on jackstands. Remove the wheels. Be sure to block the front tires. Remove the
Brake Calipers and the
Brake Discs. Clean the parking brake assembly with brake system cleaner before beginning any work. Replacement of the parking brake shoes involves washing down the brake assembly with brake cleaner, removing the front hold-down clip and the rear hold-down clip, removing the parking brake shoe adjuster, removing the lower return spring, spreading the parking brake shoes and lifting off the parking brake shoe assembly, transferring the upper return spring to the new shoes, lubricating the shoe contact points on the backing plate with high-temperature brake grease and the rear shoe hold-down clip, spreading the lower ends of the shoes apart and installing the parking brake shoe assembly, installing the lower return spring, installing the front shoe hold-down clip and the adjuster (making sure the star wheel of the adjuster is pointing towards the front of the vehicle). Clean the brake disc/parking brake drum and check it for score marks, deep grooves, hard spots (which will appear as small discolored areas) and cracks. If the disc/drum is worn, scored or out-of-round, it can be resurfaced by an automotive machine shop. After the shoes have been installed, turn the adjusting screw so the disc just fits over the new shoes. When the disc is installed, the shoes should not rub as the disc is turned. If you have a brake shoe adjusting gauge, adjust the diameter of the shoes to 0.02-inch less than that of the drum surface of the rear brake disc. Repeat this procedure for the other parking brake assembly. Install the brake discs and the brake calipers. Remove the rubber plug from the brake backing plate and, using a screwdriver or brake adjusting tool, turn the adjusting screw star wheel until the parking brake shoes start to drag as the disc is turned, then back off the star wheel until the shoes don't drag. Install the rear wheels and lug nuts, lower the vehicle and tighten the lug nuts.
