How to Resurface Brake Drums at Home

Resurfacing brake drums is an essential maintenance procedure for ensuring your vehicle's braking system operates efficiently. If you notice uneven braking or hear unusual sounds when applying the brakes, it might be time to check your brake drums. Fortunately, with the right tools and careful attention, you can resurface brake drums at home, saving money and gaining knowledge about your vehicle's maintenance.

What You’ll Need

1. Tools and Materials - Brake drum lathe (can be rented or purchased) - Safety glasses and gloves - Measuring calipers - Brake drum gauge - Brake cleaner - Clean rags - Torque wrench - C-clamp or brake spring tool (if removing shoes)

2. Preparation Begin by ensuring that you have a safe workspace. Park your vehicle on a flat surface, engage the parking brake, and wear protective gear. Gather all your tools before starting to streamline the process.

3. Remove the Brake Drum Jack up the vehicle and support it securely with jack stands. Remove the wheel lug nuts using a lug wrench and take off the wheel. Next, inspect the brake shoes and springs. If necessary, use a C-clamp or brake spring tool to remove the brake shoes carefully. This step is crucial to access the brake drum.

4. Inspect the Brake Drum Before resurfacing, check the drum for any visible damage, such as cracks or deep grooves. Use the measuring calipers and drum gauge to check for thickness. If the drum is below manufacturer specifications, it’s safer to replace it instead of resurfacing.

5. Setting Up the Lathe If your drum is suitable for resurfacing, mount it on the brake drum lathe according to the manufacturer’s instructions. Adjust the machine to ensure it cuts evenly across the surface.

6. Resurfacing Process Turn on the lathe and allow it to run, observing the cutting process. Gradually move the cutting tool across the surface of the drum, applying consistent pressure. This will create a smooth, even finish. Ensure that you do not remove too much material; maintaining the right thickness is crucial for safety.

7. Clean and Reassemble Once resurfacing is complete, clean the drum with brake cleaner to remove any debris. Reinstall the brake shoes and reattach the drum. Finally, put the wheel back on, torque the lug nuts to the manufacturer’s specifications, and lower the vehicle.

8. Test Drive After everything is reassembled, take the vehicle for a short test drive to ensure the brakes are functioning correctly. Listen for any unusual noises and check for even braking.

By following these steps, you can effectively resurface your brake drums at home. Regular maintenance will prolong the life of your brake components and enhance your vehicle's safety. Always consult your vehicle’s manual for specifications and guidance specific to your model.
