Can rust on car brakes make a scraping noise?

Rust on car brakes can cause a scraping noise when the brake pads rub against the rotors. This is because rust is a type of corrosion that can cause the metal to become rough and uneven. When the brake pads rub against the rotors, the rough surface of the rust can create a scraping noise. In addition, rust can also cause the brake pads to wear out more quickly, which can lead to further problems with the brakes. If you hear a scraping noise when you brake, it is important to have your brakes inspected by a qualified mechanic to determine if the rust is the cause of the noise.
