Vehicle disc brake of the liquid cooled type.

摘要

A brake of the self-energising liquid cooled type incorporates a pump mechanism (20) for pumping liquid from a sump (30) to a braking member (1, 2) which is slidably keyed to a shaft (3) to be braked. The pump mechanism (20) incorporates one rotatable pump member (21) which is driven from the shaft and may be housed within a pressure plate (8) which forms a part of an actuating mechanism (5) for the brake. Alternatively the pump may comprise a turbo-disc which is separate from the brake and is spaced from the stack of braking members.
