Whenever the brake shoes are replaced, the return and hold-down springs should also be replaced due to the continuous heating and cooling cycle that causes the springs to lose tension over time, potentially allowing the shoes to drag on the drum and wear at a much faster rate than normal. When replacing the rear brake shoes, use only high-quality, nationally-recognized brand name parts. Begin by loosening the wheel lug nuts, raising the rear of the vehicle, and securely supporting it on jackstands while blocking the front wheels to prevent rolling. Release the parking brake and remove the wheel, ensuring that all four rear shoes are replaced simultaneously but working on one brake assembly at a time to avoid mixing parts. Remove the brake drum; if difficult, back off the parking brake cable, remove the access hole plug from the backing plate, and use a screwdriver to push the parking brake lever off its stop, allowing the shoes to retract slightly. Tap gently on the drum with a punch and rubber mallet to loosen it, avoiding excessive force. Clean the brake assembly with brake system cleaner, avoiding compressed air. For installation, follow the reverse of removal, lubricating components as necessary, and set the preliminary shoe adjustment by turning the star wheel on the adjuster to ensure the linings are 0.05 inch less than the inner diameter of the drum. Before reinstalling the drum, check for cracks, score marks, deep scratches, and hard spots, which may require taking the drum to an automotive machine shop for resurfacing. If resurfacing is not done, remove any glaze with medium-grit emery cloth and replace the drum if it cannot be cleaned before reaching the maximum service limit. Install the brake drum on the axle flange, mount the wheel, install the lug nuts, and lower the vehicle. Finally, apply and release the brake pedal 30 to 35 times using normal force, pausing for about one second between applications, and ensure both wheels turn freely after adjustment.
