ABSTRACT:
An improved disc brake rotor is formed with fins extending between the two annular braking members which are elongated tangentially of the rotor axis and disposed in two groups lying at different radial distances from the axis. The tangential orientation of the fins minimizes the amount of material required to form the fins while achieving structural rigidity comparable to other fin arrangements which require substantially more material. The fin arrangements disclosed thus enables a substantial reduction in weight and also achieves efficient cooling air flow patterns for either direction of rotation of the rotor.
