Abstract: A rotary brake resurfacer includes a first electric motor, a geared motor speed reducer operatively associated with the first motor for outputting a reduced rotational speed and a driven shaft mounted for rotation at the reduced output speed of the speed reducer. A brake rotor to be resurfaced is mounted on the driven shaft. A second electric motor is provided and a grinder shaft is mounted for being rotated by the second electric motor. First and second grinding stones are rotatably mounted in spaced-apart relation on the grinder shaft and the griding stones are moved into contact with the braking surface of the rotating brake rotor for resurfacing the braking surface of the brake rotor. The method according to the invention includes the steps of rotating a brake rotor, rotating at least one grinding stone and engaging the rotating grinding stone with the braking surface of the rotating brake rotor for resurfacing the braking surface of the brake rotor.
