A master cylinder having a body with a bore therein delimited by a piston into a work chamber and a supply chamber. The work chamber () is connected to wheel brakes, while the supply chamber is connected to a fluid supply, through a supply duct. The piston has a shank retained by a guide ring mounted in the bore and a head bears against a thrust ring in a rest position. A first end of the supply duct is connected to the fluid supply, while a end is connected to the supply chamber. A hydraulic damping arrangement that dampens movement of the piston toward the thrust ring and includes structure for shutting off the second end of the supply duct such that brake fluid flows at a reduced flow rate from the supply chamber to the supply duct through at least one exhaust duct.

The planar abutment key (11) incorporates in its body portion (18) two flexible fingers (22) extending laterally and angularly in the direction away from the end portion (19) of the key which forms abutment arms (21) for the plunger, each finger (22) ending in a sharp angle (24), the transverse distance at rest between the sharp angles (24) being greater than the transverse width (d.sub.1) of the slot (12) in the hub portion of the assistance piston (1) in which the key (11) is housed.
