How do I get rust off car brake discs?

There is a coating of orange rust on my brakes, and I’m nervous it might interfere with my ability to stop. What should I do to get the rust off my car brake discs?

Answer
Rusty brake discs can be annoying and even dangerous if left for long enough! Luckily, you follow these steps to get the rust off your car brake discs:
  • Start by going for a quick drive to loosen the rust.
  • When you come back, jack up your car so you can remove the wheels.
  • Secure your rear wheels with a block to stop the car from rolling.
  • Remove the wheels, brake pads, and calipers.
  • Spray the brake discs with a professional rust cleaning product like WD-40.
  • Scrub the discs in circular motions with steel wool to remove the rust.
  • Try to be gentle. If you see scratches, apply less pressure.
Once you’ve removed all the rust, you can reassemble the brakes and put the wheels back in their place. Make sure to replace pads and calipers (if you removed them) before the rim. Then, lower your car slowly back to the ground and enjoy your rust-free brake discs!
