Abstract
In a fluid pressure control valve unit incorporated between a master cylinder and rear wheel brake cylinders, a spring loaded stepped sleeve member associates with a differential piston to provide a cut-off valve. In case the front-wheel braking system is not operated due to some damage, the sleeve member moves from its usual position to apply the braking pressure directly to the rear-wheel brake cylinders.
