Abstract
The assembly is of the type in which the disc has a braking surface for cooperation with a brake pad and the wheel has a radially-extending web and an axial annular surface. A centering device centers the disc relative to the axial annular surface. The disc has on the side thereof opposed to the braking surface a second surface which frictionally engages a third surface defined by the wheel of the web. The second or third surface is constituted by a material having a coefficient of friction on the third or second surface which is higher than that of the braking surface of the disc on the brake pad so that, upon braking, the disc does not slip relative to the wheel.
