Typically, your brake rotor should last between 30,000 to 70,000 miles. If you use and maintain your vehicle well, the rotors should last more than that. The braking system is one of your car's busiest and most hardworking systems. Because of how frequently and vigorously it works, some parts of the system will need replacement occasionally. Brake rotors, also known as brake discs, wear out faster because of the friction and pressure they create to halt the car. When the rotors begin to malfunction, you will notice signs such as annoying noise and vibration but do not wait for these signs before you change them. Factors such as your driving behavior, the quality of your present rotor, atmospheric conditions, and so on also affect how long rotors last.
