Abstract
The invention relates to a motor vehicle braking system, comprising a brake pedal (P) to generate brake pressure in an hydraulic fluid, a brake pressure booster (12) operated by differential pressure and adapted to be actuated by a first valve (V.sub.1) which is pressurized mechanically by the brake pedal (P), and a first sensor (S.sub.1) to detect the pressure generated by the brake pedal. A second sensor (S.sub.R, S.sub.L) is provided to detect vehicle deceleration or rotational retardation of braked wheel, and a data processing unit serves to compare the data determined by the sensors (S.sub.1, S.sub.R, S.sub.L) and to generate a control signal in response to the result of the comparison for a second valve (V.sub.2) which is controllable electrically and by which a pressure difference is adjustable in the brake pressure booster (12).
