Disclosed is a hand brake mechanism for a rail vehicle. The hand brake is operated by rotation of one of a pair of hand wheels (70,75). Rotation of the hand wheel causes rotation of a screw (62) within brake actuator (60), which in turn moves a nut (66) in a linear manner. Movement of the nut causes a pair of cables (40 and 50) to operate two wheel brake mechanisms (30), one on each wheel of an axle (20). Cable (50) is operated by pushing or pulling its inner part (54) whereas cable (40) is operated by pushing or pulling its outer sheath (42) while its inner part (44) is held at the actuator (60). This action causes a corresponding pushing or pulling at the cable's brake mechanism end.
