* Corrosion: This can occur when the rotors are exposed to moisture and salt. Corrosion can weaken the rotors and make them more susceptible to damage.
* Impact damage: This can happen if a foreign object, such as a rock, hits the rotor. Impact damage can crack or break the rotors.
* Wear and tear: This is the natural result of using the brakes. As the brake pads wear down, they can damage the rotors.
