A floating disc brake assembly comprises a hub and a rotor in mating alignment therewith through one or more interlocking lobes that are alternatingly arranged about an outer peripheral edge of the hub and an internal edge of the rotor. The rotor is coupled to, and disposed circumferentially around, the hub. As a friction element is applied to the rotor to decrease rotation thereof during a braking operation, the interlocking lobes transmit brake torque from the rotor to the hub through a gap existing therebetween. The gap retards heat flow. The gap also permits radial float. Differing hub and rotor widths, or a floating clearance between a fastener and the hub, both permit axial float. Warpage and knockback of the rotor are reduced.
