Abstract: A disc brake rotor having a central hat portion for coupling a rotor to a vehicle wheel for rotation about a central axis, an inboard brakeplate for receiving a first friction surface and an outboard brakeplate for receiving a second friction surface. A plurality of L-shaped rib members extends from the hat for coupling the inboard brakeplate to the hat and a second plurality of L-shaped members radially extend from the hat for coupling the outboard brakeplate to the hat. First plurality of ribs is longer than the second plurality of ribs. The second set L-shaped members is located intermediate of the edges of the inboard and outboard pluralities to enhance the heat transfer of the braking operation.

Abstract: A method of manufacturing a corner module assembly wherein a wheel hub is attached to the knuckle and the knuckle is held by a clamping force applied through locator pads and thereafter a radial mounting surface and first and second bosses on the knuckle are machined into parallel alignment with the bases of the locator pads. After a rotor is fixed against the machined radial mounting flange, the first and second braking surfaces on the rotor finished machined, if necessary, into the same parallel alignment with the bases such that first and second friction member retained in a caliper are located in parallel alignment with the first and second braking surfaces when the caliper that is attached to the first and second bosses on the knuckle and finally attachments surfaces on the knuckle are machined. This sequentially machining substantially eliminates assembly tolerances of the corner module assembly.
