Abstract
A rotatable member for a brake of the liquid cooled type comprises a disc provided on opposite sides with annular braking faces. The disc incorporates a plurality of angularly spaced liquid supply slots which extend through the material of the disc and radially outwards from a position inwardly of the inner peripheral edges of the braking faces. A portion at the inner end of each slot is of a circumferential length greater than the remainder of the slot. The member may comprise a braking member for the brake, or it may be separate from the brake and act as a pump member in the form of a turbo disc.
