ABSTRACT:
A method and a multi-circuit brake booster for feeding back disruptions of any arbitrary kind, even of an associated anti-skid brake system, to a then-changed brake pedal characteristic, the influence on the brake valve triggering being effected via a travel simulator device. The transmitting member in the travel simulator device is a travel simulator spring enabling a predetermined idle pedal travel, and this spring responds whenever, in response to an arbitrarily generated disruption signal, a lockable storage element assumes its other position and mechanically engages a transmitting member in the chain from brake pedal actuation to brake valve slide actuation in an arresting manner. Upon reaching a predetermined amount of biasing, as a result of the further compression of the travel simulator spring, the opening of the brake valve then takes place abruptly, with a corresponding increase in brake pressure and a corresponding increase in vehicle deceleration.
