A piston stroke adjusting arrangement for disc-type friction clutches or brakes used most advantageously in forging machines and presses where rapid engagement and disengagement of clutches and brakes is essential. The arrangement includes a housing and a cylinder flange, fast with each other, the cylinder receiving the piston reciprocating therein. Axial displacement of the piston is limited by a washer arrangement in a groove made in the housing and having radially running recesses of different depths. The flange of the cylinder carries an abutment engageable in one of the radial recesses of the washer. The disclosed construction simplifies the structure of the arrangement, as a whole, and provides for both rapid and reliable adjustment of the piston stroke value.
