See full text

A master for a hydraulic actuating element, with a cylinder, in which a piston is displaceably mounted, and a hand lever, with which the position of the piston in the cylinder can be influenced, and a fastening element which comprises a clamping part shaped complementarily to the inner cross section of the handlebar, which is equipped for being fastened in the handlebar by means of an internal clamping. Furthermore, the invention relates to a master, in which the hand lever and the piston are connected by a push rod, which comprises a first longitudinal portion, which is provided with an external thread, which engages in an internal thread on the hand lever, so that the distance between piston and hand lever can be adjusted by turning the push rod, and wherein the push rod comprises a second longitudinal portion, which is provided with a polygonal outer cross section, which bears against at least one second spring element. Finally, the invention relates to a master, in which the piston made of a plastic material seals off the cylinder to the outside with a wiping lip, which is unitarily joined to the piston.
