BRAKE BOOSTER HAVING INCREASED TOLERANCE

摘要

A brake booster with a mechanical actuator (3) and automatic clearance adjustment, using a variable-length spacer (5) including an elongate nut (7) and a screw (9) both biased on unscrewing by a preloaded spring (16) in a housing (17). The second end (7b) of the nut (7) is guided by a cylindrical sleeve (18) provided with a radial flange (18a) trapped between the spring (16) and the housing (17).
