How to Use Brake Cleaner on Drum Brakes

Brake cleaning is an essential part of regular vehicle maintenance, especially for those who want to ensure optimal performance and safety. When it comes to drum brakes, using brake cleaner effectively can help improve braking performance and extend the life of your brake components. Here’s a step-by-step guide on how to use brake cleaner on drum brakes safely and effectively.

What You Need

Before you start, make sure you have the necessary tools and materials - Brake cleaner (aerosol can) - Safety goggles - Gloves - Old rags or paper towels - A lug wrench - Jack and jack stands - A clean working area

Safety First

Before you begin working on your drum brakes, it’s crucial to prioritize safety. Ensure you wear safety goggles and gloves to protect your eyes and skin from chemicals in the brake cleaner. Work in a well-ventilated area to avoid inhaling fumes.

Step-by-Step Guide

1. Prepare Your Vehicle Park your vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels (if you’re working on the front brakes) or the front wheels (if working on the rear brakes).

2. Loosen the Lug Nuts Use a lug wrench to slightly loosen the lug nuts on the wheel you’ll be removing. Do not completely remove them yet.

3. Raise the Vehicle Using a jack, lift the vehicle off the ground and secure it with jack stands to ensure stability while you work.

4. Remove the Wheel Finish unscrewing the lug nuts and remove the wheel to expose the drum brake assembly.

5. Inspect the Brake Components Before applying the brake cleaner, take the time to inspect the brake shoes, drums, and other components for wear or damage.

6. Apply Brake Cleaner Shake the can of brake cleaner well and spray it generously onto the brake drum and the brake shoes. Make sure to cover all surfaces thoroughly. The brake cleaner will dissolve grease, grime, and brake dust, helping to restore the performance of your brakes.

7. Wipe Excess Cleaner Use an old rag or paper towel to wipe away any excess brake cleaner and debris. Be careful not to touch the brake shoes or drums with your bare hands, as oils from your skin can affect braking performance.

8. Reassemble the Wheel Once everything is clean and dry, reattach the wheel and tighten the lug nuts by hand.

9. Lower the Vehicle Remove the jack stands and lower the vehicle back to the ground using the jack. Give the lug nuts a final tighten in a star pattern for even distribution.

10. Test Your Brakes Before driving, press the brake pedal a few times to ensure proper contact and function. Take your vehicle for a short test drive to confirm everything is working as it should.

Conclusion

Using brake cleaner on drum brakes is a straightforward process that can significantly enhance braking efficiency and safety. By following these steps, you can maintain your drum brakes effectively and extend their lifespan, ensuring a smoother and safer driving experience. Remember, regular maintenance is key to keeping your vehicle in top condition.
