The brake fluid flows from the master cylinder to the cut valve and the inlet valve
to supply fluid pressure to the relevant wheels.

ylinder, and o
pens the outlet solenoid valve to return the brake fluid from the

wheel cylinders to the buffer chamber. This causes the wheel cylinder fluid pressure
to decrease. Then the system activates the pump motor to return the brake fluid
from the buffer chamber to the hydraulic unit reservoir.

The system closes the inlet and outlet valves to hold the fluid pressure in the wheel
cylinders. The brake fluid, which is pumped from the hydraulic unit reservoir, is
supplied to the inlet valve. At this time, excessive fluid is returned through the relie

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.
NOTE: *: When the ASC is operating while the brake pedal is
depressed, the suction valve turns on and off according to
the brake fluid amount supplied to the buffer chamber.
