Loosen the wheel lug nuts, raise the front or rear of the vehicle, and support it securely on jackstands while blocking the wheels at the opposite end to prevent rolling. Release the parking brake and remove the wheel and brake drum. If the drum is difficult to pull off, ensure the parking brake is fully released, then apply penetrating oil at the hub-to-drum joint, allowing it to soak before attempting to remove the drum again. If it remains stuck, retract the brake shoes by removing the plug from the backing plate and turning the adjusting screw star wheel with a screwdriver to move the shoes away from the drum, marking the drum's relationship to the hub for balance. If the brake shoes are hanging up due to wear, use a screwdriver or adjusting tool to turn the star wheel and retract the shoes. Clean the brake assembly with brake cleaner and position a drain pan to catch fluid and residue, avoiding the use of compressed air. Inspect and replace dual leading type brake shoes or leading/trailing type brake shoes as needed, paying attention to the installation order. Before reinstalling the drum, check for cracks, score marks, deep scratches, and hard spots; if any issues are found, take the drum to an automotive machine shop for resurfacing, as professionals recommend this with each brake job. If resurfacing is not an option, remove any glaze with sandpaper or emery cloth. Install the brake drum on the axle flange and check the preliminary brake adjustment, ensuring the drum fits snugly over the shoes. Mount the wheel, install the lug nuts, and lower the vehicle. Make several forward and reverse stops while operating the parking brake to adjust the brakes for satisfactory pedal action, and carefully check the operation of the brakes before driving.
