Abstract
A hydraulic parking brake assembly for a railroad vehicle braking system comprising a hydraulic actuator capable of being mounted on or engagable with the braking system and a lever arrangement connected to the hydraulic actuator which moves in accordance with activation of the hydraulic actuator and initiates a braking sequence. The lever arrangement is associated with the force transfer lever of the air cylinder such that upon movement of the lever arrangement, a force is applied to this force transfer lever causing this force transfer lever to rotate in a counterclockwise direction to apply the appropriate forces to the push rod within the brake cylinder and to a force transmitting member within the braking system to effect activation of the parking brake assembly.
