ABSTRACT:
In a fluid control valve unit for a crossed piping brake system, a pair of inertia-controlled valves are provided to independently control respective braking fluids supplied to the right and left rear-wheel brake cylinders at a rate of pressure increase lower than the rate of pressure increase in a tandem master cylinder. The control valve unit is further provided therein with a movable stepped spool which is moved to forcibly close one of the inertia-controlled valves when braking fluid cannot be supplied to one of the rear-wheel brake cylinders and a stepped piston which is moved to forcibly close the other inertia-controlled valve when braking fluid cannot be supplied to the other rear-wheel brake cylinder.
