How to Clean Rear Drum Brakes

Cleaning your rear drum brakes is an essential maintenance task that helps ensure your vehicle's braking system functions effectively. Over time, brake dust, debris, and moisture can accumulate in the brake drum, leading to reduced performance and potential issues. Here's a step-by-step guide to help you clean your rear drum brakes properly.

Tools and Materials Needed

Before getting started, gather the following tools and materials

- Car jack and jack stands - Lug wrench - Screwdriver - Brake cleaner spray - Shop towels or rags - Wire brush or old toothbrush - Safety goggles and gloves - Brake lubricant (optional)

Step 1 Prepare Your Vehicle

1. Park Safely Choose a flat, safe location to work on your vehicle. Turn on the hazard lights to alert others. 2. Loosen Lug Nuts Before lifting the vehicle, use the lug wrench to slightly loosen the lug nuts on the rear wheels. Do not remove them completely at this stage. 3. Jack Up the Vehicle Use a car jack to raise the rear of your vehicle. Place jack stands under the vehicle to secure it and ensure your safety while working.

Step 2 Remove the Wheel

1. Take Off the Lug Nuts Now that the vehicle is securely elevated, finish removing the lug nuts and take off the wheel. 2. Inspect the Brake Drum Check for any visible damage or irregularities on the brake drum. If you notice severe wear, consider replacing the drum instead of cleaning it.

1. Access the Drum Some drums may be held in place by retaining screws. If present, use a screwdriver to remove these screws. 2. Pull Off the Drum Carefully pull the drum away from the wheel hub. You may need to gently tap it with a rubber mallet if it is stuck.

Step 4 Clean the Brake Components

1. Spray Brake Cleaner Use brake cleaner spray to soak the interior of the drum and the brake shoes. This will help loosen brake dust and debris. 2. Scrub the Surface Take a wire brush or an old toothbrush and scrub the inside of the drum vigorously. Be cautious not to damage the brake shoes or components. 3. Clean the Brake Shoes Wipe the surface of the brake shoes with a clean rag or towel. If they appear heavily contaminated with oil or dust, consider replacing them.

Step 5 Reassemble the Brakes

1. Inspect Hardware Examine any springs or clips connected to the brake assembly. If they look worn or damaged, replace them. 2. Reattach the Drum Place the cleaned drum back onto the wheel hub, ensuring it fits properly. 3. Secure with Screws If your drum has retaining screws, put them back in place.

Step 6 Reinstall the Wheel

1. Put the Wheel Back On Align the wheel with the hub, and hand-tighten the lug nuts. 2. Lower the Vehicle Carefully remove the jack stands and lower the vehicle back to the ground. 3. Tighten Lug Nuts Once the car is on the ground, use the lug wrench to tightly secure all the lug nuts.

Step 7 Test Your Brake System

Before hitting the road, pump the brake pedal a few times to ensure proper engagement. This also allows the brake shoes to settle against the drum properly.

Conclusion

Cleaning your rear drum brakes is a valuable skill that can save you money and enhance your vehicle's safety. Regular maintenance, such as cleaning and inspecting your drums and shoes, can prolong their lifespan and improve the overall performance of your braking system. If you encounter any serious issues or uncertainties during the cleaning process, don't hesitate to consult a professional mechanic. Remember, safety should always come first!
