Abstract
A disc brake system ( ) comprises a disc ( ), and a hub ( ) which is arranged to rotate about an axis ( ) thereof. The hub ( ) comprises a mounting portion ( ) which is generally in the shape of a hollow cylinder. The system ( ) also comprises grooves ( ) and teeth ( ) by which the disc ( ) is mounted on the external surface of the mounting portion ( ) for rotation with the hub ( ) as a unit about the axis ( ) and the disc ( ) can perform axial sliding movement on the hub. The hub ( ) carries vanes ( ) arranged so that, during rotation of the hub ( ) about the axis ( ), the vanes act to force air into the interior of the mounting portion ( ). The mounting portion ( ) has openings ( ) therethrough arranged so that air forced into the interior of the mounting portion ( ) passes through the openings and flows over said disc ( ).
