Abstract
In one aspect of the present disclosure, a commercial vehicle brake rotor is provided that includes a unitary, one-piece annular body having a central axis of rotation. The annular body includes vents and a braking portion having inboard and outboard braking surfaces. The annular body includes a central mounting flange having through openings to receive studs of a wheel hub. The through openings each have at least a portion thereof extending axially intermediate the inboard and outboard braking surfaces of the annular body. The annular body further includes inboard and outboard air inlets in communication with the vents.
