Abstract
PURPOSE: To facilitate detection of failure and improve reliability by a constitution in which the output of failure signal is generated when pressure signal generated with the discharge pressure of a liquid pressure pump exceeding a predetermined value after generation of drive signal of the said pump is not generated within a predetermined time.
CONSTITUTION: This device is provided with electromagnetic three position change-over valves 8a, 8b as liquid pressure controlling valves for controlling brake liquid pressure in brake cylinders 6a, 6b, a reservoir 7 and a liquid pressure pump 12. In this case, a permanent magnet 14 is fixed to the right end of a piston 31 of a valve unit 20 disposed in a pressure liquid supply pipe path 4a while a magnetism responsing switch 35 is opposed and fixed to said magnet 14 to a cover member 32 to close a switch 35 with the piston 31 moving rightward when discharge pressure of said pump 12 reaches at least a predetermined value. When the switch 35 is not closed within a predetermined time after the drive of said pump 12, i.e. pressure signal is not generated, failure signal is generated in an electronic unit 9.
