Beschreibung
Zusammenfassung:	(Case No. 7086) A hydro-pneumatic brake actuator having a friction element positionable by the power piston during the brake application stroke through a lost-motion connection therewith to establish a stop to limit movement of the power piston during a brake release and thereby provide a predetermined brake shoe clearance. In an alternate embodiment, a leaf spring is carried by the friction element to provide a cushioned stop for the power piston to prevent inadvertent displacement of the friction element, by reason of wheel out-of-roundness imparting a "kick-back" force on the power piston.
