Abstract
A rotor is provided for use with a vehicle brake assembly that includes a forcing member operable to urge a friction member into mechanical communication with the rotor to thereby oppose movement of the same. The rotor includes a rotor body with an annular rim portion having first and second opposing contact faces. One or more loose-mass damper systems are interposed between the first and second contact faces, and operable to dissipate kinetic energy directly therefrom. Each of the loose-mass damper systems includes at least one mass operable to repeatedly impact against first and second inner faces respectively opposing the first and second contact faces to reduce oscillation of the rotor. Reducing oscillation of the rotor is independent of temperature and pressure. The loose-mass damper systems are preferably oriented proximate to an outer peripheral edge of the annular rim portion generally circumferentially equidistant from one another.
