<p>1. A master cylinder for at least one brake circuit, comprising a piston (10) cooperating on the one hand by means of an annular reaction member (18) of elastomeric material with a central flange (17) of a tubular member (9) adapted to be connected to a piston (7) of a servomotor (1), and on the other hand with an actuating push-rod (12) comprising at least a first abutment area for engaging the annular reaction member, characterized in that a second abutment area is formed at least partially by at least one thrust element (21; 21') actuated by the push-rod (12) and axially extending across a corresponding orifice (20; 21') formed in said flange (17).</p> |
