Surface rust on brake rotors is common and can often be removed with a simple cleaning process.
Simple Steps to Remove Brake Rotor Rust
Removing light rust from your brake rotors typically involves cleaning the affected surface. Here's a straightforward method based on the provided reference:
What You'll Need:
- Brake cleaner
- Steel wool
- Jack and jack stands (or lift)
- Lug wrench
The Process:
Follow these steps carefully to clean the rust from your rotors:
- Safely Lift Your Vehicle: Begin by safely lifting the front or rear end of your car using a jack and securing it with jack stands. Ensure the vehicle is stable before proceeding.
- Remove the Wheel: Use a lug wrench to loosen and remove the lug nuts, then take the wheel off the hub to expose the brake rotor.
- Apply Brake Cleaner: Spray the entire surface of the brake rotor generously with brake cleaner.
- Scrub the Rust: Use steel wool to vigorously rub across the rusty surfaces of the rotor. Focus on the face of the rotor where the brake pads make contact.
- Rinse Again: Once the visible rust is removed, spray the rotor again with brake cleaner to wash away rust particles and residue.
- Dry and Reassemble: Allow the rotor to dry completely. Then, replace the wheel onto the hub and tighten the lug nuts securely in a star pattern. Repeat the process on the other side if necessary.
This method is effective for removing surface rust that appears due to moisture, especially after the car has been sitting for a while. For pitting or deep rust, professional inspection may be required.
Rust on the rotor surface can sometimes cause a slight noise or vibration when braking initially, but often wears off after a few stops. However, actively removing it ensures a clean braking surface from the start.
