Abstract
A brake actuator having a service brake coupled to an emergency/parking brake through a lost-motion connection that allows the service brake to be applied independently of the emergency/parking brake includes a slack adjuster, the pawl of which is withheld from engagement with the teeth of the slack adjuster ratchet wheel by an interrupter vane whenever the emergency/parking brake is actuated, to thereby disable the slack adjuster.
