A master cylinder for use in a hydraulically actuated clutch or brake system of a motor vehicle, includes a casing formed with a bore, and a piston unit axially displaceable within the bore. The piston unit includes a piston-shaft sleeve received in the bore and having one end formed with a bottom to define an interior, at least two retainer shells received in the interior of the sleeve free of play, and a piston rod having a spherical head swingably mounted to the retainer shells and provided to respond to a manual actuation of a pedal. The retainer shells are each formed at a pedal-proximate end of the piston-shaft sleeve with a spherical recess to define a ball socket in which the spherical head snaps in and is received in form-fitting manner.
