ABSTRACT:
A hydraulic brake booster adapted to vehicles having a manually operable control valve to control pressure increase in the booster for attaining the available braking fluid pressure in the brake wheel cylinders of the vehicles. In the booster is employed a control device to hold off a reaction force on the pedal to actuate the booster so that a properly controlled brake feel is transmitted to the vehicle operator at an initial stage of actuation of the booster. An earlier pressure rise is attained in the wheel cylinders within an otherwise vainly consumed period of time as a timelag and accordingly a safe and reliable braking operation is performed.
