An automatic parking brake (210) is provided which includes a rail car brake beam (206) and a housing (250) associated with the rail car brake beam. The automatic parking brake includes a locking nut (256) positioned in the housing and having a post (208) that extends out of the housing. A rail car brake lever (204) is secured to the post so that the locking nut will rotate with the rail car brake lever. A locking sleeve (260) is moveable between a locked position, where the locking sleeve engages the locking nut and prevents from the nut from rotating, and a released position, where the locking sleeve is disengaged from the locking nut and the locking nut is free to rotate. A spring (282) provides a force biasing the locking nut into the locked position. [Fig. 15 to accompany abstract]
