The invention is directed to a ventilated brake rotor, including a hub mounting face, a rotor ring having two faces, and a hub wall connecting the hub mounting face to the rotor ring. The rotor ring has alternately faced conical passages disposed at an angle less than 90 degrees to the face of the rotor ring. Each passage passes through both the first and second face of the rotor ring, and when the ventilated brake rotor is rotated each passage acts as a conduit for air flow through the rotor ring.
