4 signals the switching of the directional control solenoid valve 31 from a predetermined non-operating position to a working position. This signal device 3
In the simplest construction, the control of 4 is effected by an electrical contact piece that is mechanically operated directly by the valve piston of the solenoid valve 31. However, this signaling device can also be controlled by evaluating the position of the first brake piston 14 and simultaneously detecting the position of the brake pedal 12. For this purpose, a momentum sensor 35, which captures the sliding amount of the brake piston 14 via a detection syringe 36, and a momentum sensor 22 for the brake pedal position are coupled to each other, for example, by an AND gate 37, in which the momentum is detected. The output signal of sensor 22 is adapted to be reversed. The output signal of this AND gate 37 controls a signaling device 34, that is, it causes an indication signal to be generated by the signaling device 34 when the momentum sensor 35 issues an output signal and the momentum sensor 22 does not issue an output signal. It has become. This means that the brake piston 14 is connected to the solenoid valve 31 without operating the brake pedal 12.
This indicates that the sliding movement is based on the direct pressure supply to the boosting chamber 17 via the booster chamber 17.

It is also possible to have a continuous connection from the control valve outlet 28 to the booster chamber 17 by means of the connecting conduit 29 in its working position.
