Abstract
PURPOSE: To facilitate detection of failure and improve reliability by providing a switch operated when brake liquid reserved in a reservoir exceeds a predetermined value, and generating failure signals with the output of the switch.
CONSTITUTION: This device is provided with electromagnetic three position change-over valves 10a, 10b, 10r as liquid pressure controlling valves for controlling brake liquid pressure in brake cylinders 4aW4d, reservoirs 9f, 9r and liquid pressure pumps 11f, 11r. The reservoir 9f(9r) is provided with a piston 23 moved downward against a spring 25 when brake liquid pressure supplied to a reserve chamber 30 from a port 21 exceeds a predetermined amount. A movable member 32 is urged by a leg 26 of the piston 23 moved downward so that a contact 33 contacts both conductors 42, 43 to close a switch 45f(45r), which generates failure signals in an electronic unit 13.
