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.

A disc for a disc brake comprising two annular members arranged coaxially with respect to each other and with respect to a central hub, a central web radiating from the central hub and extending between said annular members, generally radially extending vanes projecting from each side of the central web and interconnecting said central web with each said annular members, and pillars separate and distinct from said vanes and also projecting from each side of the central web and interconnecting said central web with each said annular member, said vanes extending for part of the radial extent of said annular members, and each of said pillars having a radial extent less than said vanes and being located in a radial region not occupied by said vanes.
