Abstract
An actuator assembly includes first and second components which are movable away from each other to initiate application of a brake, upon pressurization of a pressure space between the components. An automatic adjuster assembly co-operating with the components comprises an axially extending member including a piston portion working in a bore in the first component of which the end of the bore remote from the pressure space is vented to atmosphere, a friction ring co-operating with the member and coupled to the component for relative movement through a distance corresponding to desired braking clearances, a spring for biassing the member away from the first component to maintain it in engagement with the other component when the pressure space is pressurized and until the pressure acting on the member overcomes the force in the spring whereafter the member moves in the opposite direction until that movement is arrested by the co-operation of the ring with the component upon release of the brake, the spacing between the components is determined by the co-operation between the component and the member.
