Loosen the wheel lug nuts, raise the rear of the vehicle, and support it securely on jackstands while blocking the front wheels to prevent rolling. Release the parking brake and remove the wheel, ensuring that all four rear brake shoes are replaced simultaneously, but work on one brake assembly at a time to avoid mixing parts. Follow the illustrations for the brake shoe replacement procedure, marking the relationship of the drum to the hub to maintain dynamic balance, and install the adjuster lever over the pin on the front shoe. If the brake drum cannot be easily removed, ensure the parking brake is fully released; if it remains stuck, retract the brake shoes by removing the plug from the backing plate and using screwdrivers to adjust the star wheel. Before reinstalling the drum, check for cracks, score marks, deep scratches, and hard spots, as any of these conditions may require resurfacing at an automotive machine shop. If resurfacing is not an option due to excessive wear, new drums will be necessary, but at a minimum, remove any glaze with emery cloth. Install the brake drum on the axle flange, followed by the wheel and lug nuts, then lower the vehicle and tighten the lug nuts to the specified torque. Make several forward and reverse stops and operate the parking brake to adjust the brakes until satisfactory pedal action is achieved, and carefully check the operation of the brakes before driving.
