ABSTRACT:
A brake actuator includes an annular housing (10b) having first and second opposite radial faces (A and B). Cavities are formed in the housing (10b), some opening onto face (A) and some onto radial face (B). Two pistons (16) are disposed in each of the cavities and are movable under the influence of fluid pressure exerted from within the respective cavities to a braking position where the pistons (16) extend axially away from the cavity. The piston (16) bear against a backing plate of respective brake pads (68) forcing the brake pads (68) against brake discs (54and56). By providing cavities on both faces (A and B) of the housing (10b), an actuator can simultaneously apply brake pads to two spaced apart rotating discs (54and56). A plurality of actuators can be coupled together to act on a plurality of axially spaced apart brake discs to form a multi-pad multi-brake system.
