ABSTRACT:
A disc brake system for a motorcycle having a wheel hub includes a brake disc fixed on one side of the hub to rotate with the hub. A caliper member is fixed to the motorcycle for braking engagement with the brake disc. A side panel of substantially the same diameter as the disc covers the brake disc and has a cooling air introduction port. A radial fan for inducing radial outward air flow from the brake disc is positioned adjacent the periphery of the brake disc and fixed to rotate with the hub. The hub includes a plurality of bosses extending towards the brake disc. The disc brake contains cutout portions for engagement with the bosses. The radial fan includes a ring attached to the ends of the bosses on the other side of the brake disc from the hub to retain the brake disc on the bosses. A radial flange extending from the hub covers the inner periphery of the radial flow fan.
