A multi-part piston for a brake saddle of a hydraulically and/or mechanically and/or electromechanically actuated disk brake is described herein. The piston is a pot open on one side and including a base and a wall attached thereto in one piece. The base can be impinged by brake pressure coming from the inside of the pot so that an outward-facing abutting surface of the base can be pressed against a brake lining. The inside of the pot receives at least one pressure piece associated with a parking brake mechanism. For simplified manufacture in the form of a modular piston system for use in various applications, it is proposed that the pressure piece and the base comprise conical surfaces facing one another for transferring braking pressure.
