How to Paint Rear Brake Drums A Step-by-Step Guide

When it comes to maintaining your vehicle, one important aspect often overlooked is the aesthetic appeal of your brake components. Painting your rear brake drums not only enhances the look of your wheels but can also provide a degree of protection from rust and corrosion. This guide will walk you through the necessary steps to achieve a professional-looking finish on your rear brake drums.

Materials You’ll Need

Before you start, gather the following materials

- Brake drum cleaner (or brake cleaner spray) - Sandpaper (120 to 240 grit) - Primer (high-temperature, if possible) - Brake drum paint (high-temperature rated) - Masking tape - Newspaper or plastic sheeting - Gloves - Safety goggles - Paintbrush or spray nozzle

Step 1 Safety First

Safety should always be your top priority when working on your vehicle. Start by ensuring that the car is parked on a level surface and that you’ve engaged the parking brake. Wear gloves and safety goggles to protect your hands and eyes from dust and paint.

Step 2 Remove the Wheel

Using a lug wrench, loosen the lug nuts slightly, then jack the vehicle up and securely place it on jack stands. Once the vehicle is raised, remove the lug nuts completely and take off the wheel to expose the rear brake drum.

Before painting, it’s essential to clean the rear brake drum thoroughly. Use brake drum cleaner or a similar solvent to remove any grease, dust, or old paint. This step is crucial, as it ensures that the paint adheres properly. After cleaning, allow the surface to dry completely.

Step 4 Sand the Surface

Once dry, use sandpaper to gently scuff the surface of the brake drum. This roughens the surface, promoting better adhesion for the primer and paint. Start with a rougher grit (around 120) and gradually move to a finer grit (240). Avoid sanding too aggressively, as this can damage the drum. After sanding, clean the drum again to remove any sanding dust.

Step 5 Tape Off Areas

Carefully apply masking tape around the edges of the brake drum, as well as any adjacent components that you don’t want to paint. This will help create clean lines and protect other parts from overspray.

Step 6 Apply Primer

Using a high-temperature primer, apply a thin, even coat to the brake drum. If you’re using spray primer, hold the can about 6-12 inches away from the surface for an even spray. Allow the primer to dry according to the manufacturer's instructions. A second coat may be necessary for full coverage.

Step 7 Paint the Brake Drum

Once the primer is completely dry, it’s time to paint. Choose a high-temperature brake drum paint, preferably in a color that complements your vehicle. Similar to priming, apply a thin coat on the drum, allowing it to dry before deciding if a second coat is necessary. Two light coats often look better than one heavy coat.

Step 8 Reassemble the Wheel

After the paint has dried completely, carefully remove the masking tape. Reattach the wheel, ensuring that you securely fasten the lug nuts. Lower the vehicle back to the ground and give the lug nuts another check to ensure everything is tight.

Conclusion

Painting your rear brake drums is a straightforward process that can enhance the overall appearance of your vehicle while providing durable protection against rust. By following these steps and taking the time to do it right, you’ll achieve a finish that not only looks great but can last for years to come.
