ABSTRACT:
The invention is directed to a ventilated disk brake rotor made of integrally cast metal or allow that includes a central hub having a cylindrical main part, and a pair of friction plates extending radially from the central hub in parallel with one another. The friction plates are disposed in mutually spaced apart relationship by use of a plurality of radial ribs. Further, the friction plates are directly attached to an outer circumferential surface of the cylindrical main part of the central hub at their base ends. As a result, the generation of cracks and premature wear are prevented through the increased rigidity of the friction plates without an increase in the weight of the disk brake rotor.
