The lever (7) rests on a movable fulcrum (12) provided by a moveable support unit (10) that is displaceable in radial direction relative to the rotation axis of the clutch or the disc brake and which is displaceable using a motor-driven (15) spindle (14. The moveable support unit (10) rests on a raceway (11) and includes two roller sets (20.1, 20.2) each with rollers (21, 22, 22.1, 22.2).
