Rust on brake discs is a common issue, especially if your vehicle has been sitting unused for a while or exposed to the elements. While light surface rust is normal and often wears off with driving, excessive rust buildup can reduce braking efficiency and compromise safety. Here is a step by step guide to easily remove rust using just a wire brush and coarse steel wool. Here’s how.

Why Remove Rust from Brake Discs?

• Prevents brake noise and vibration – Rust buildup can lead to uneven braking, causing squeaking or juddering.

• Improves braking performance – A clean surface ensures proper contact between the brake pad and disc.

• Extends the life of brake components – Removing rust helps prevent deeper corrosion and pitting.

What You’ll Need

• Coarse steel wool, coarse steel wool works best, this can be found here.

Step-by-Step Guide to Rust Removal

Step 1: Secure the Vehicle

Before working on your brakes, make sure your vehicle is on a flat, stable surface. Use a jack and axle stands to lift the car safely, then remove the wheels to expose the brake discs.

Step 2: Dry Scrub with a Wire Brush

Take a heavy-duty wire brush and begin scrubbing the brake disc’s surface. Use firm pressure to remove loose rust, dirt, and debris. Focus on the areas where rust is most visible.

Step 3: Smooth with Coarse Steel Wool

Once the majority of the rust is removed, take coarse steel wool and rub the disc in a circular motion. This helps remove finer rust particles and smooths out the surface for optimal brake performance.

Step 4: Wipe Down the Surface

After scrubbing, use a clean, dry cloth to wipe off any remaining rust dust or metal particles. Avoid using water or chemicals, as moisture can lead to further rusting.

Step 5: Reassemble and Test

Once the brake disc is rust-free, reattach the wheels, lower the car, and take it for a short test drive. Applying the brakes a few times will help further clean the surface and ensure smooth braking performance.

Preventing Future Rust on Brake Discs

• Drive your car regularly – Light surface rust forms when a vehicle sits unused, other problems can occur if your car has been sitting for a while.

• Store in a dry area – Moisture accelerates rusting, so parking in a garage helps or any place away from the elements.
