A hub rotor assembly includes a hub, a rotor supported by the hub and a plurality of fasteners that connect the rotor to the hub and allow relative movement between the rotor and the hub. The hub rotor assembly of the invention focuses on a brake hub and rotor assembly that uses a floatation element associated with a fastener to fasten the rotor to the hub while allowing the rotor to move or float relative to the hub. The rotor thus fastened is permitted to move or float in a limited manner with respect to the hub. This reduces the need for precise balancing due to float self-balancing. Such floatation reduces first and second order thermal distortion by allowing the rotor to thermally expand and also accommodates and significantly reduces the temperature variation and thermal distortion across the rotor surface during braking. The assembly is particularly suited for commercial highway vehicles.
