ABSTRACT:
A brake disk is fixed to a wheel hub to rotate therewith, and axially spaced bearings support the wheel hub on an axle. A non-rotary caliper member extends through a central opening in the brake disk and carries pads which engage opposite surfaces of the brake disk when hydraulic pistons are energized. A portion of the caliper member encircles a portion of the wheel hub, and a wide supporting surface is provided to minimize tilt or cant of the caliper member. In a preferred embodiment a support rim encircles the portion of the wheel hub to provide wide spacing of supports for the caliper member. Another embodiment places the central plane of the brake disk in the center of one of the wheel hub bearings and in the central portion of the cylindrical rim. Limited axial movement of the caliper member after wear of the brake disk and friction pads is accommodated by resilient bushings at both ends of a torque arm which prevents rotary movement of the caliper member.
