We had a customer come in, complaining of a vibration, most notably when braking. They had recently had a brake job performed at a well-known chain. Upon inspection of the tires, brakes and rotors, it was discovered that the rotors had not been serviced properly, and were warped. When a rotor is warped, it is the same as a vinyl record warping, where there are waves in the surface. They cannot be seen easily but can be felt in the vibrations. As seen in the photos, there are areas where the metal is shinier than other spots, where the metal is wearing more from the pads.
To correct this problem, we use a brake lathe to resurface the rotors. It will cut a thin layer off the surface of the rotor. This may need to be done several times, each time taking a small amount off until it is even, while taking the least amount off.
This video is of the first pass of the lathe on one of the problem rotors. Notice how it is only removing a small uneven area. This is the top of one of the more pronounced waves.
Rotors should usually be resurfaced when the brakes are serviced, unless they are at the minimum thickness or severely damaged. At which point they should be replaced.

We are looking for Mechanics! Must have at least 5 years experience and Certification is preferred. Stop by and talk with us if interested.
