Abstract
The brake motor subassembly with automatic play compensation limitation by way of a stepped pilot piston (20), comprising a first cylindrical peripheral surface of larger diameter (21) sliding in an inner bore (7) of the control piston (1) and a second cylindrical peripheral surface of reduced diameter (24) interacting sealingly slideably with an annular gasket (17) in the piston (1), has an intermediate radial shoulder (26) which, during the movement of the pilot piston (20) because of the opposing effective cross-sections (s.sub.1, s.sub.2), interacts with the annular gasket (17) so as thereby to present a new effective surface (s.sub.3) preventing the continuation of the movement of the pilot piston (20) and thus avoiding the compression of the elastic member (11) which normally stresses the automatic compensation nut (14).
