Abstract
A brake of the self-energising liquid cooled type incorporates a pump mechanism for pumping liquid from a sump to a braking member which is slidably keyed to a shaft to be braked. The pump mechanism incorporates one rotatable pump member which is driven from the shaft and may be housed within a pressure plate which forms a part of an actuating mechanism 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.
