Abstract
A brake rotor for use in a vehicle disc brake assembly includes an inner mounting flange and an outer annular friction disc connected together by a circumferential hat. The inner mounting flange is formed having a center pilot hole and a plurality of lug bolt receiving holes equally spaced circumferentially about the pilot hole. The outer annular friction disc includes a pair of annular friction plates which are connected together in a spaced apart relationship by a plurality of fins spaced circumferentially around the friction disc. Each successive pair of the fins defines a cooling passageway between the friction plates. Each of the fins extends in a generally radial direction and includes an innermost end, an outermost end, and a pair of spaced apart outer side wall surfaces. Each fin defines a symmetric center axis between the outermost end and the innermost end thereof. The pair of spaced apart outer side wall surfaces define smooth progressively increasing curved outer surfaces extending radially outwardly from adjacent the innermost end to adjacent the outermost end thereof.
