To prevent vibrations and uneven wear of a brake resulting from runout of the brake rotor, a reliable wheel bearing assembly with a brake rotor is proposed which needs no troublesome runout adjustment at a car assembling factory. The assembly includes an outer member having two raceways on its inner circumferential surface, an inner member having raceways each provided opposite a respective one of the two raceways, and rolling elements arranged in two rows between the outer and inner members. One of the outer and inner members is provided with a wheel mounting flange, and the brake rotor is mounted to the wheel mounting flange. The runout variation of a side of the brake rotor is maintained within a standard value with a fixed-side member as a datum.
