Abstract
A ventilated disc brake rotor has first and second discs separated by radially extending ribs. The first disc has a thin wall section, and a peripheral thick wall section having an increased wall thickness increased by a raised portion raised from the inside surface of the first disc toward the second disc. The thick wall section extends radially from the outer periphery over a radial range of about ⅓ of the radial width of the braking friction surface of the first disc.
