Abstract

PURPOSE: To control the brake liquid pressure to a preset level by separating a mechaniam, which corresponds to a ball valve to detect the decelration, and a control valve and by detecting the liquid pressure and the deceleration thereby to generate electric signals.
CONSTITUTION: When a vehicle reaches a preset deceleation, a lead switch 13 is turned on so that the resultant electric signals are fed to a memory/operational device. Both the data, in which the electric signals are stored as a trigger, and the signals from a converter 18 are subjected to operation by the memory/operational device so that the reference signals for determining the valve closing pressure are fed to a differential amplifier 20. The signals of the amplifier 20 and the control valve 1 are compared, and the when the difference inbetween reaches to a level to cutting the braking liquid to be fed to a rear wheel, signals are generatd in an AND circuit 21. Then, an AND condition is satisfied with the electric signal of the lead switch 13 so that the signals from the circuit 21 are amplified by an amplifier 22 and are fed to a solenoid 9 together with the valve closing signals tereby to close the valve 7.
