Brake rotor checking

Check the brake rotors for wear any time the brakes are serviced. Rotors that are scored with sharp ridges, warped, worn irregularly or cracked should be replaced.

Brake rotors should always be resurfaced in pairs, with an equal amount of material removed from both sides of each rotor. Table a lists the dimensions for resurfacing rotors. Rotors which fail to meet these requirements should be replaced.

On original equipment rotors, the minimum thickness dimension can be found stamped into the rotor's hub.
