The invention relates to a master cylinder for an actuating device of a clutch or a brake of a motor vehicle, including a cylinder housing having a pressure cylinder section, as well as a piston mounted movable relative to the cylinder housing, wherein the piston is arranged inside the pressure cylinder section in an actuation state in order to control a fluid pressure in a fluidically sealed pressure chamber by a sealing device on the piston side, and is arranged in a pressureless state such that the pressure cylinder section is fluidically connected to a retention system, wherein a seal of the sealing device is configured, and attached to the piston, such that it rests on a seal protection area of a stop element at least in a parking position in the pressureless state; as well as a method for mounting such a master cylinder.
