What to do if there's rust on your brake rotors

Your brake rotors may start to rust after using your car for a while, especially after a thunderstorm or after you wash your car.

KEY TAKEAWAYS

  • Is it okay if brake rotors rust?

    There is probably nothing to worry about if you have observed any surface rust on your brake rotor. Normal driving will remove any surface rust. The problem becomes more serious, though, if the rotor has developed pitting due to the rust.
  • How can I prevent surface rust on brake rotors?

    Driving your car regularly, even in short distances, is one of the easiest ways to stop your brake rotors from rusting.
  • It is a good habit to perform visual checks before taking your car out so you can determine whether general vehicle maintenance is required.

    Is it okay if brake rotors rust?

    Should rusty brake rotors be replaced?

    Brake rotors do not last a lifetime. Whenever you apply the brakes, the rotors gradually lose their durability. The quality of the rotors, the types of brake pads being used, how quickly the rotors cool down, your driving technique, and the amount of exposure your rotors have to moisture are all factors that affect how quickly rotors wear.

    It is recommended to replace the rotors every time new pads are changed in to properly set the new pads and stimulate a new initial friction layer.

    Brake rotors must also be replaced if you notice heavy rust, scoring, grooves, and vibrations when braking.

    Will brake pads be damaged by rusty rotors?

    The brake pads receive slight damage from the rust when they rub against the discs and remove the surface rust. There will not be any negative impact in the immediate future, but the rust will eventually result in damage that wears out the brake pads.

    What causes brake rotors to rust so quickly?

    It all comes down to the rotor's material. Your brake rotors are probably made of cast iron, which is susceptible to rusting, unless you have a rare vehicle with carbon-ceramic brakes. If the discs are in contact with moisture or water, iron is rapidly oxidized, and rust will develop on their surface.

    Regardless of ride height, the rotors of most vehicles on the road, whether SUVs or sedans, will rust.

    How can I prevent surface rust on brake rotors?

    Driving your car regularly, even in short distances, is one of the easiest ways to stop your brake rotors from rusting. By using the brakes, you may naturally eliminate surface rust, which prevents oxidation from building up and causing damage.

    Moreover, make sure your rotors are of high quality.

    Also, keep your vehicle out of the elements, ideally in a garage or other covered area, to reduce the likelihood of rust developing on your brake rotors. This will protect your car from moisture buildup and lessen the possibility of corrosion problems.

    Regular car washing is also a good way of maintaining your vehicle in good condition since it gets rid of dirt and other contaminants that wind up in areas they should not. You may prolong the overall operating life of your car with regular regular cleaning.
