ABSTRACT:
The method and apparatus for honing and treating the pad engaging surfaces of vehicle brake rotors or discs consisting of engaging the rotor surface with a plurality of moving abrasive elements mounted upon flexible resilient stems wherein a smooth finished surface is formed. The abrasive elements are rotated about an axis which may be coincident with the brake rotor axis of rotation during machining, or may be offset and parallel thereto, to produce a basket weave machining pattern. A plurality of hone holders may be used when the hone axis of rotation is offset relative to the rotor axis whereby both of the rotor's surfaces may be simultaneously finished. The practice of the invention also permits the braking surfaces of aluminum alloy rotors to be oxidized to form a hard, wear resistant finish thereon.
