ABSTRACT:
A brake unit for automotive vehicles includes a low-pressure brake booster and hydraulic tandem brake master cylinder fastened thereto between the splashboard of the vehicle and the brake booster. The brake pedal force is transmitted via a pressure sleeve extending through a primary piston and a secondary piston of the master cylinder onto a control valve disposed inside the booster. The boosting force generated by a movable wall of the booster is transmitted via an annular reaction disc of elastic material, which is disposed in a hub member of the movable wall, via an adjustable stop nut onto a central tie rod. The tie rod at the pedal-side end thereto is in engagement with the primary piston of the master cylinder by means of a radial extension.
