Abstract
A master cylinder comprising a body (4) pierced with a bore (5) closed on a first side by an end (6) and on a second side by a piston (7). The piston (7) slides in the bore (5) to delimit a pressure chamber (8). The pressure chamber (8) is connected by a pressure pipe (12) to at least one brake motor through an outlet (11) therein. The chamber (8) and the pressure pipe (12) together delimiting a working volume filled with a hydraulic fluid. The working volume is partially delimited by a leak-off device (19) which is responsive to an impact to selectively allow hydraulic fluid to leak off toward the outside of the working volume.
