ABSTRACT:
An improvement in a conventional air-operated diaphragm spring brake is provided by a guide (100) being disposed in registry with an aperture (26) in a service brake housing (16). A push-rod (10) extends from a diaphragm (58) within the housing (12) through the bushing (102) to pivotably connect to a slack adjuster (6). The bushing (102) serves to maintain the push-rod (10) at a preselected angle relative to the slack adjuster (6) when the push-rod is in the inoperative position.
