Abstract

The brake or coupling system () comprises a first piston () arranged in a first piston cylinder () thereby forming a first piston chamber () and a second piston () arranged in a second piston cylinder () thereby forming a second piston chamber (). The first piston () is adapted to be displaced between a braking position and a rest position. The first piston () is spring biased in the direction of its rest position, and the second piston () is adapted to adjust a distance (X) provided between a friction element () and a rotatable element () in the rest position of the first piston () by means of adjustment of a volume of hydraulic fluid trapped in the second piston chamber (). At least one spring element is arranged to act between the first and second pistons (). The first and second pistons () are so arranged that a hydraulic pressure in the first and second piston chambers (), respectively, will urge the first and second pistons () in opposite directions, thereby biasing the at least one spring element.
