Abstract
A method and apparatus for controlling brake pressure having a brake booster and a pedal-actuated brake valve, in order to effect parallel feeding of the pressure medium fed via the brake valve into a primary main booster chamber. A feed valve is arranged such that displacement volumes in the wheel brake cylinders, in particular, are equalized by means of direct pressure feeding. The triggering of the feed valve is effected based on the result of comparison of travel or pressure variables detected by transducers in the vicinity of the master brake cylinder.
