Abstract

It is frequently important for the piston of a hydraulic piston-and-cylinder assembly, in particular the brake piston of a disc brake, which is slidably arranged within a cylinder bore to ensure a true-to-size mounting position of the piston inside the cylinder bore. Especially in the case of brake pistons of a disc brake, this determines the efficiency of provisions on the brake piston for reducing the occurrence of brake noises. According to the present invention, a key-type accommodation is provided on the piston which permits engagement by a matingly configured mounting means or mounting tool and, thus, renders possible the defined positioning of the piston within a cylinder bore.
