FIELD: automotive industry. SUBSTANCE: brake lever has worm wheel 3 and worm screw 4. On the worm screw is clutch wheel 6 that forms a clutch together with the screw. Adjusting load is transmitted from the outer reference point through gear wheel 16, wheel of holder 17, and control screw 20. The common axle of the three members is perpendicular to the worm screw. The wheel of the holder can rotate by spring 18 with respect to the gear wheel by an angular distance corresponding to the clearance. Under the action of torsion spring 17 one-sided clutch 19 engages between wheel 17 and adjusting screw 20. Torsion spring 18 is preliminary compressed. EFFECT: enhanced reliability. 2 cl, 5 dwg
