Rusty brakes are a common problem, especially in wet weather. As winter winds down and we anticipate spring rains, car maintenance tasks such as dealing with rusty brakes are on our minds. While surface rust on brake rotors and calipers is usually not a significant safety concern, it can be unsightly and, if left untreated, lead to more serious problems.
Taking care of your brakes is an essential part of car maintenance. Here’s what you need to know about rusty brakes.
Causes of Rusty Brakes
There are a few different things that can cause brake rotors and calipers to rust:
- Exposure to moisture: Brake rotors and calipers are made of iron, which is a metal that rusts easily when exposed to moisture. This is why rusty brakes are more common in areas with high humidity or frequent rain.
- Lack of use: If you don’t drive your car very often, the brake rotors and calipers will have more time to rust. This is because the brake pads don’t rub against the rotors, which helps keep them clean and free of rust.
- Damaged brake pads: If your brake pads are worn down or damaged, they won’t be able to protect the rotors from rust. This is because the brake pads act as a barrier between the rotors and the moisture in the air.
What to Do About Rusty Brakes
If you notice that your brakes are rusty, there are a few things you can do to fix the problem:
- Clean the rust off the rotors and calipers: You can use a wire brush or a rust remover. After you’re finished, rinse the rotors and calipers thoroughly with water.
- Apply a rust-resistant coating: Rust-resistant coatings are available at most auto parts stores and will protect the rotors and calipers from oxidation.
- Replace worn brake pads: New brake pads will perform better and help prevent further rust from forming on the rotors and calipers.
Preventing Rusty Brakes
There are a few things you can do to prevent your brakes from rusting in the first place:
- Drive your car regularly: Driving helps keep the brake pads rubbing against the rotors, keeping them clean and free of rust.
- Park your car in a dry place: Parking in a garage or carport will protect your car from the elements.
- Get your brakes inspected regularly: A qualified mechanic can inspect your brakes for rust and other problems.
