The system closes the cut valve to shut the fluid channel from the master cylinder to the wheel cylinders, and opens the suction valve to open the fluid channel from the master cylinder to the hydraulic unit reservoir. The brake fluid, which is pumped from the master cylinder to the hydraulic unit reservoir, is supplied to the wheel cylinders.

NOTE: At this time, the hydraulic unit reservoir cannot operate due to the fluid pressure from the master cylinder.
