Beschreibung
Zusammenfassung:	The present invention provides a brake actuation and adjuster system comprising means for applying brake actuation pressure both to a brake actuator member and to a pump. The pump is arranged to pump pressure fluid to an adjuster control valve and an adjuster actuator, and the brake actuator member is arranged to be moved by said brake actuation pressure to then open the adjuster control valve against the pressure of the pressure fluid after the brake actuator has moved to a predetermined release position. Thus, in one embodiment, brake actuation pressure primes the pump causing the pump to force pressure fluid to the adjuster actuator. If adjustment is necessary, it is effected until the adjuster control valve is opened to release the pressure fluid. Thus a simple, independent adjuster arrangement is provided which does not affect available brake performance.
