摘要： A master cylinder (1) having a bore (3) fitted with at least one piston (4, 5) and at least one seal (19, 20, 21, 22). The seal (19, 20, 21, 22) is partially stiffened by a reinforcement member (25). In order to retain the piston (4,5) in the bore (3) a groove (31) is located on a circumference of the piston (4,5) against which the sealing member (25) bears with the piston (4,5) in a rest position to retain the piston (4,5) in bore (3).

摘要： A primary piston composed of a skirt and an intermediate back wall having a rear face receiving the servobrake thrust rod and a forward face for the telescoping rod and the spring pushing the secondary piston. The front of the skirt has longitudinal grooves open in front and closed in the rear. The thickness of the skirt beneath the grooves and the part of the skirt between two successive grooves in the peripheral direction form a front face enabling the principal piston to push the secondary piston. The principal piston is made of a single piece of plastic material.
