Abstract
An actuating unit for anti-lock brake systems for automotive vehicles comprised of a vacuum brake power booster and a tandem master brake cylinder, wherein on failure of the primary pressure chamber a force is simulated which is opposed to the actuating force. For this purpose, a compression spring (28) is arranged in the booster housing (10) which is brought into force-transmitting engagement with the input member only after a predetermined distance of travel of the input member has occurred (3, 23).
