A master piston for a hydraulic vehicle brake is arranged in a master cylinder of the hydraulic vehicle brake and is movable in a reciprocal manner along a master piston longitudinal axis. The master piston has at least one piston element and a seal which is injection molded onto the piston element. The master piston has at least one guide portion for guiding the master piston in the master cylinder. The guide portion is elastically deformable at least in some portions in a radial direction to the master piston longitudinal axis. The guide portion is formed at least partially from a different material from the piston element. The piston element, the seal and the guide portion are produced together by a multi-component injection molding method. A method for producing the master piston is disclosed.
