Abstract

A lever system for actuating a clutch in the power train of a motor vehicle or of a disc brake, including: a lever (7) with a first side (7.1) rotatably supported on a pivot (8) and with a side (7.2) in functional connection with a pressing means (6). 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). Each of the roller set (20.1, 20.2) includes at least three rollers (21, 22, 22.1, 22.2) and at least two of the rollers (22.1, 22.2) include approximately equal first diameters.
