PURPOSE: To attain the stability of an anti-locking device, in a brake system in which the actuation of a retarder is prohibited from the moment a request for regulation is sent to the anti-locking device for a wheel, by restarting the retarder only from the moment a new request for braking is made. CONSTITUTION: A foot-operated control box 4 inputs each of the information outputted from the anti-locking device 5 of a wheel and from an electronic tachometer 6. The anti-locking device 5 outputs each of information for regulation and alarm to the control box 4 through an adjusting relay 7. A lamp 8 involving a plurality of pressure switches 1-n is combined with a braking circuit and connected to a retarder 9 through a connector box 10. A first pressure switch 1 outputs the information for braking to the control box 4, therefore, the control box 4 permits foot-operated control, and an electromagnetic or a static output relay 11 is switched, thereby restarting the retarder 9 only from the moment a new request for braking is made. |
