How to Get Rust Off Brake Drums

Brake drums are crucial components of a vehicle's braking system, used primarily in older cars with drum brakes. Over time, brake drums can develop rust due to exposure to moisture, road salt, and road grime. Not only does rust look unsightly, but it can also affect the performance and safety of your brakes. If you notice rust on your brake drums, don't panic. Here’s a step-by-step guide on how to effectively remove rust from brake drums and ensure your vehicle performs safely.

Materials You Will Need

Before you start, gather the following materials - Jack and jack stands - Lug wrench - Wire brush or steel wool - Sandpaper (medium and fine grit) - Rust-inhibiting primer (optional) - Rust-resistant paint (optional) - Degreaser or brake cleaner - Safety goggles and gloves - Old rags or shop towels

Step 1 Safety First

Before starting any work on your vehicle, safety should be your top priority. Wear safety goggles and gloves to protect your eyes and hands from debris and chemicals. Park your vehicle on a level surface, engage the parking brake, and ensure the engine is off.

Step 2 Lifting the Vehicle

Using the lug wrench, loosen the lug nuts on the wheel that covers the brake drum. Then, use the jack to lift the vehicle off the ground. Once elevated, place jack stands under the vehicle for added safety. Remove the wheel to access the brake drum.

Step 3 Inspect the Brake Drum

Take a moment to inspect the condition of the brake drum. Look for areas of heavy rust and any signs of pitting or severe corrosion. If the rust is solely surface-level, it can generally be removed. However, if there are deep pits or structural issues, consider consulting a professional mechanic.

Step 4 Remove Surface Rust

Using a wire brush or steel wool, scrub the rusted areas of the brake drum. This should effectively remove loose rust and debris. After that, utilize medium-grit sandpaper to smooth out the surface, followed by fine-grit sandpaper for a refined finish. Clean the drum thoroughly with a degreaser or brake cleaner to remove any dust and grease generated during sanding.

Step 5 Protect Against Future Rust

To prevent rust from reoccurring, consider applying a rust-inhibiting primer followed by a coat of rust-resistant paint once the drum is clean and dry. This extra protective layer can considerably prolong the lifespan of your brake drums.

Step 6 Reassemble Everything

Once you've finished cleaning and protecting the brake drum, it’s time to reassemble everything. Carefully replace the wheel, ensuring that the lug nuts are tightened securely. Lower the vehicle back down to the ground and use the lug wrench to tighten the lug nuts to the manufacturer's specifications.

Step 7 Test Your Brakes

Before hitting the road, it’s essential to test your brakes to ensure they are functioning correctly after maintenance. Press the brake pedal a few times to seat the brake components properly and check for any unusual sounds or sensations.

Conclusion

Removing rust from brake drums is a relatively simple yet important maintenance task that can enhance the efficiency and safety of your vehicle. Regular inspections and maintenance can help prevent rust buildup, ensuring your brakes remain in top working condition. If you encounter severe rust or any uncertainties during the process, do not hesitate to consult a professional. Ensuring your vehicle's brake system is in good condition is critical for your safety and that of others on the road.
