Abstract
A ventilated disk brake includes a pair of brake pads which is substantially the same as the prior art, and a rotor. The rotor has a brake-pad engaging portion in which a pair of brake-pad engaging walls are formed to be pressed between and by the pair of brake pads. A plurality of cooling ribs extend radially between the pair of brake-pad engaging walls. The cooling ribs are formed in such a manner that the weight distribution thereof is ununiform in the peripheral direction thereof along the brake-pad engaging portion. For example, the cooling ribs can be different in thickness, length and/or arrangement interval. such a design can be made on the basis of empirical data.
