Devices and methods for imparting a nondirectional finish to brake rotors and similar articles. Such devices include two disks which are suspended against the rotor faces. The device suspends the disks with freedom of rotation in all directions and freedom of translation in a direction parallel to the rotational axis of the rotor. A follower presses each disk against its corresponding rotor face at a place located in the area between the disk centers and the rotor rotational axis. Rotor rotation causes the disks to spin, and an abrasive surface on the inside face of each disk provides a nondirectional finish as the disks float freely on the rotor surfaces about their follower contact points.
