Abstract

An apparatus comprising an operating mechanism having at least a portion thereof engageable with at least one gear of a gear assembly disposed in a housing member of a hand brake assembly for operating such gear assembly. A source of fluid pressure is connected to the operating mechanism for periodically supplying a pressure to such operating mechanism. A control device is connected to the source of pressure for initiating the supply of such pressure to the operating mechanism. A further control device is connected to the source of pressure for regulating the supply of such pressure to the operating mechanism thereby causing an automatic application of such brake by the hand brake assembly. An additional control device is connected to the source of pressure for stopping an automatic application of such brake in case of an emergency or a reversal of an unintended activation.
