A brake rotor (110) adapted for use in a vehicle disc brake assembly includes an inner mounting flange portion and an outer annular disc portion (114) connected thereto by a circumferential hat portion (116). The outer annular disc portion defines an outboard brake surface (122) and an inboard brake surface (124). The outboard brake surface has an inner peripheral surface (122a) and the inboard brake surface has an inner peripheral surface (124a). The inner peripheral surface of the outboard brake surface is connected to the hat portion by a plurality of first ribs (130) and the inner peripheral surface of the inboard brake surface is connected to the hat portion by a plurality of second ribs (132).
