Abstract
The present invention provides a disc for a disc brake, the disc comprising two annular members arranged coaxially with respect to each other and joined together by generally radially extending vanes and pillars, which project from a central web located between the annular members. The vanes extend for part of the radial extent of the annular members, and the pillars are located in a region not occupied by the vanes and preferably radially beyond the vanes. Power absorption and noise generation is reduced considerably as a result of the reduced vane overall diameter, as compared to a disc of like diameter with the conventional long radial vanes. However, the desired cooling is maintained due to the surface area presented by the combination of shorter vanes and pillars.
