ABSTRACT:
A wheel bearing assembly is provided which can suppress brake judder. A film is disposed between the brake rotor-mounting surface of the wheel mounting flange and an abutment surface of a brake rotor to fill a gap therebetween to suppress the deformation of the brake rotor. Also, by concentrating the contact force between the wheel-mounting flange and the brake rotor when a disc wheel of the wheel is tightened to the hub bolts to a portion near the hub bolts, the contact between the wheel-mounting flange and the brake rotor on the surfaces between the hub bolts is suppressed so that undulation of the flat surfaces between the hub bolts will not cause deformation of the brake rotor.
