ABSTRACT OF THE DISCLOSURE A slack adjuster for connecting an air actuated piston rod to rotate a cam shaft in a vehicle brake system has a worm gear mounted to rotate in a housing and connected to the cam shaft, the worm gear and the cam shaft rotating together about a first axis. A shaft rotatable in the housing about a second axis perpendicular to the first axis has a worm intermediate its ends engaged with the worm gear. A drive and a coupling are mounted coaxially to rotate on the shaft and a ratchet interconnects the drive and the coupling for allowing the drive to rotate about the shaft axis relative to the coupling in only one direction. A slip surface between the coupling and the shaft slips when a predetermined rotational force is exerted between the coupling and the shaft. A clevis connects the housing to the piston rod at a predetermined point spaced from the first axis, a link is connected to the clevis at a point spaced from the connection between the clevis and the housing, and the link and the drive are connected for rotating the drive and the coupling as the vehicle brakes are applied.
