Abstract
A brake pressure control device for a road vehicle with a hydraulic brake system has a pneumatic braking force amplifier which is provided with a switch-over device which switches ever the braking force amplifier to operation with increased amplification factor when the speed with which the driver actuates the brake pedal exceeds a threshold value .phi..sub.s. In the axial force transmission train leading from the brake pedal via a reaction piston of the control part, via a reaction element and via the actuating piston of the braking force amplifier to the main cylinder. A rigid force transmission element is in mechanical parallel connection to a flexible transmission element and associated with which there is a position engaged in the force transmission train as the basic position for the judicious braking operation, and an actuation device, which responds when the threshold value .phi..sub.s of the pedal actuation speed is exceeded and then disengages the distance piece from its supporting position.
