Q:

How long do brake rotors last?

A:

Quick Answer

While disc brakes tend to last anywhere from 30,000 to 50,000 miles, the length of time brake rotors typically last depends on several different factors. These factors include how often the brakes are applied, how hard they are applied, the weight of the vehicle and how often the brakes have been serviced.

Full Answer

It is important to perform regular maintenance to increase the life span of brake rotors. Check brake fluid frequently. Change the brake fluid periodically. Inspect the brake pads regularly, and change them when you can no longer see much of the pad. Periodically inspect the rotors for wear. Replace the rotors when there are signs of wear or cracks.

  • Q:

    How does brake rotor thickness impact driving safety?

    A:

    Brake rotor thickness serves an important role in driving safety; thin rotors may increase the risk of brakes cracking and fading, ultimately causing braking failure. The acceptable and recommended amount of brake rotor thickness varies among different automobile types and makes, but all maintain a certain level of rotor thickness, which increases vehicle stability, stopping time and structural integrity. Brake rotors must maintain a certain level of thickness to absorb heat and allow heat dissipation; unable to perform this function, thin rotors may cause extensive damage and present a driving risk.

  • Q:

    Why does a car shake when applying the brakes?

    A:

    If the steering wheel or car shakes when the brakes are applied, it is almost certain that the problem lies with the rotors. This is an important distinction as steering wheel or car vibration can happen for a number of reasons, but if it only happens when the brakes are applied, this isolates the problem. Worn brake pads are another possibility, but if the pads have recently been replaced, then this leaves only the rotors as suspects.

    What does a brake system diagram show?

    A:

    A typical brake system diagram shows the location and configuration of the master cylinder, the distribution of the lines, valves, hoses and cables, and the configurations of the discs and rotors. Other features of a brake system diagram include parking brake elements and vacuum components.

  • Q:

    Why is brake pad thickness measuring important?

    A:

    Brake pad thickness is important because, over time, the friction between the brake pads and the rotors wears down the pads, necessitating replacement. When brake pads are less than 3 mm thick, they should be replaced with fresh pads. Since they are always replaced in pairs, only one pad needs to be worn down to necessitate the replacement of both pads.
