Brake rotors work with your vehicles brake pads to safely stop your car every time you hit the brake pedal. The rotor rotates with the wheel, and when you apply the brake pedal the brake pad clamps down on the road, or to bring your vehicle to a stop. Brake rotors should be replaced between 50,000 and 70,000 miles or sooner if you feel a vibration in the steering wheel or on the brake pedal. Failure to replace your rotors when needed can cause brake failure or an accident.
