Brake Rotors

Brake Rotors

Brake rotors will not last forever, they wear down a little bit every time the brake pedal is applied. How fast the rotors wear depends on a lot of variables including the type of brake pads, quality of the materials, how fast the rotors cool down, driving style, exposure to moisture and road salt.

Most original equipment brake rotors used to be designed with enough thickness to last at least two or more pad replacements. Most new cars have thinner rotors to save weight and could be worn to the minimum by the first time the brake pads need to be replaced. Normally both rotors need to be replaced because they will usually have the same amount of wear. Even if one side is “good enough”, it is wise to replace both brake rotors at the same time to maintain even braking as any difference in rotor thickness will cause the brakes to pull to one side.

As inexpensive as rotors are now, it is affordable enough to simply replace the rotors rather than paying to resurface them. New brake rotors should be ready to install right out of the box. There is no need to resurface them as this may actually produce runout and will reduce their service life. If your vehicle originally included brake rotors with a separate hub and disc (composite rotors) they can safely be replaced with cast iron brake rotors. Cast rotors are more rigid than composite rotors, but they may slightly affect steering and handling on some vehicles. For those customers who are interested in increased brake performance and safety, we recommend premium brake rotors over the standard replacement brake rotors.
