How to Clean Rear Drum Brakes

Cleaning rear drum brakes is an essential maintenance task that can significantly improve your vehicle's stopping performance and extend the lifespan of the braking system. While it may seem intimidating, with the right tools and guidance, it can be done effectively at home. Here’s a step-by-step guide on how to clean rear drum brakes safely and efficiently.

Tools and Materials Needed

Before you start, gather the following tools and materials

Step-by-Step Instructions

1. Preparation Start by ensuring your vehicle is parked on a flat, stable surface. Engage the parking brake to prevent any movement. It's also recommended to wear safety goggles and gloves to protect yourself from dust and debris.

2. Lifting the Vehicle Using a lug wrench, loosen the lug nuts on the rear wheels. Afterward, use the jack to lift the rear of the vehicle and secure it with jack stands. Once the vehicle is safely elevated, remove the lug nuts and take off the rear wheels.

3. Removing the Drum To access the brake components, you’ll need to remove the brake drum. Look for retaining screws holding the drum in place. If the drum is stuck, you may need to tap it gently with a hammer to loosen it. Once free, carefully remove the drum to reveal the brake assembly.

4. Inspecting the Components With the drum removed, inspect the brake shoes, springs, and other components for wear and damage. If any parts look excessively worn, consider replacing them.

5. Cleaning the Brake Assembly Spray brake cleaner generously onto the brake shoes and drum. The brake cleaner helps to remove dust and debris that accumulates over time. Use a soft brush or a small wire brush to scrub away any stubborn grime. Be cautious not to damage the brake shoes while cleaning.

6. Reassembling the Drum After cleaning, allow the brake components to dry completely. Once dry, carefully reinstall the brake drum. Make sure it sits flush against the backing plate. If applicable, reattach any retaining screws.

7. Reinstalling the Wheels Place the rear wheels back on the hubs and hand-tighten the lug nuts. Lower the vehicle back to the ground and use a torque wrench to tighten the nuts to the manufacturer’s specifications.

8. Testing the Brakes Before taking your vehicle back on the road, pump the brake pedal several times to ensure the brake shoes are properly seated against the drum. This will help restore normal brake function.

Conclusion

Cleaning your rear drum brakes is a straightforward process that can enhance your car's braking performance. Regular maintenance reduces the risk of brake failure and can save you money on professional services in the long run. Remember to consult your vehicle’s manual for specific instructions related to your make and model. If you’re ever unsure about the condition of your braking system, don’t hesitate to seek professional assistance. Safe driving starts with reliable brakes!
