1. A wheel hub of a corner assembly for a vehicle wherein the wheel hub is attached to a stationary member though a bearing, a wheel is attached to the wheel hub, a rotor for a brake system is secured to the wheel hub and a caliper is attached to the stationary member, said wheel hub having a body with an axial bore that extends from a first end to a second end, a peripheral surface with a flange thereon located adjacent said first end with the wheel and the rotor being attached to said flange and a bearing surface that extends from said second end toward said flange with the bearing being located on the bearing surface such that a perpendicular relationship is established between an axis of said bearing and first and second faces on the rotor and as a result during rotation of said wheel hub a desired space relationship is maintained between first and second faces on the rotor and corresponding first and second friction members retained by the caliper, said flange being characterized by being located adjacent a first annular surface on said first end and having a scalloped torque receiving surface adjacent a first radial surface with said torque receiving surface separated from an annular peripheral surface by a second radial surface, and said rotor being characterized by a first radial member that is offset from a second radial member on which the first and second engagement faces are located by a cylindrical member, said first radial member having an inner peripheral surface with a plurality of arcuate projections thereon that are complementary to said scalloped torque receiving surface of said flange, said cylindrical member of the rotor having an inner arcuate groove that extends from said first radial member toward said second radial member, said arcuate projections being mated with said scalloped torque receiving surface such that said first radial member engages said second radial surface to establish said perpendicular relationship between the first and second engagement faces on said second radial member of the rotor; and clip means attached to said annular peripheral surface on said flange and engaging said arcuate groove on said cylindrical member to provide a resultant force that resiliently urges said first radial member toward said second radial surface to sustain said perpendicular relationship.
