Abstract
A slack adjuster for a fluid-actuated brake comprises a slack adjuster collet (24) having a tubular skirt and an enlarged ring section. The enlarged ring section has opposed axial stop faces notched therein that define a conical lift surface facing the tube axis. A forward stop face has a conical or beveled surface arranged to engage the conical or beveled surface on one stop face of the collet when the collet carried by the actuator rod reaches the forward stop face and a retraction stop face has a conical or beveled surface arranged to engage the conical or beveled surface on the other stop face of the collet when the collet carried by the actuator rod reaches retraction stop face. The conical or beveled surfaces are configured so that when they engage, the force of the collet on the push rod is reduced.
