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