Abstract

An apparatus for monitoring brake condition for an air actuated diaphragm spring brake actuator provides a visual or audible signal when brake wear causes a brake push rod to move past a pre-determined distance with respect to the brake actuator housing. The indicator includes an engaging mechanism to retain the indicator in its operative position irrespective of subsequent movement of the push rod. A continuous record of brake failure or serious brake wear or misalignment is thereby provided.
