Abstract:
A multi-piece sound dampened brake rotor comprises a relatively light weight hub with a hub flange and a heavier rotor body with a sound damping insert and a rotor body flange. The hub and rotor body are attached at their flanges. The flanges may be mechanically attached such as with bolts. Or the hub and rotor may be attached by casting the hub of a lower melting metal alloy against the rotor body and rotor body flange. The rotor body may have vanes for air cooling and a sound damping insert may be incased in either or both body portions sandwiching the vanes.
