How to Remove Rust from Brake Drums
Rust can be a significant issue for brake drums, especially in regions where moisture and salt are prevalent. Over time, exposure to the elements can lead to the formation of rust, which can compromise the effectiveness of the brakes and create safety hazards. However, removing rust from brake drums is a manageable task that can be accomplished with some simple tools and materials. This article will guide you through the process step-by-step.
Tools and Materials Needed
Before you begin, gather the following items
1. Safety goggles and gloves 2. Jack and jack stands 3. Lug wrench 4. Wire brush or sandpaper (medium-grit) 5. Rust remover (optional) 6. Brake cleaner 7. Clean rag 8. High-temperature spray paint (optional) 9. Protective grease (optional)
Step-by-Step Guide
1. Safety First
First and foremost, ensure your safety by wearing safety goggles and gloves. This will protect your eyes and hands from debris and rust particles.
2. Prepare Your Vehicle
Using the lug wrench, loosen the lug nuts on the wheel corresponding to the brake drum you intend to work on. Then, use the jack to lift the vehicle and secure it on jack stands. This is crucial for safety, as working under a car that is not properly supported can lead to serious accidents.
Once the vehicle is safely elevated, finish removing the lug nuts and take off the wheel to expose the brake drum.
4. Inspect the Brake Drum
Examine the brake drum for any significant damage beyond surface rust. If you notice any deep pitting or severe corrosion, it might be necessary to replace the drum rather than just clean it.
5. Remove Surface Rust
Using a wire brush or medium-grit sandpaper, begin scrubbing the surface rust off the brake drum. Be thorough, ensuring that you remove all loose rust and debris. If the rust is particularly stubborn, a rust remover solution can be applied according to the manufacturer’s instructions to assist in the process.
6. Clean the Area
Once you have removed the rust, clean the brake drum area using brake cleaner. This will remove dust, oil, and other contaminants that could further corrode the drum or interfere with braking performance. Afterward, wipe down the drum with a clean rag to ensure a smooth surface.
7. Apply Protective Coating (Optional)
If you wish, you can apply a high-temperature spray paint to the brake drum to provide a barrier against future rust development. Ensure that the paint is rated for high-temperature applications, and allow it to dry completely before reassembling.
8. Reassemble the Wheel
Once the brake drum is clean and any protective coating has dried, it’s time to replace the wheel. Position the wheel back onto the hub, hand-tighten the lug nuts, and then lower the vehicle back to the ground. Use the lug wrench to securely tighten the lug nuts in a star pattern to ensure even fitting.
9. Test the Brakes
Finally, before driving your vehicle, pump the brakes a few times to ensure they are functioning correctly. Listen for any unusual sounds and check for any signs of malfunction.
Conclusion
Removing rust from brake drums is a practical task that can enhance your vehicle's safety and performance. Regular maintenance, including rust checks, can prolong the life of your brake components. If the rust appears to be more than surface level or if you’re uncomfortable performing these tasks, consider consulting a professional mechanic to ensure your vehicle remains safe on the road. Regular care and attention will go a long way in keeping your brake system in optimal condition.
