Emergency braking (ABS activated)
1. Depressurized state
When the front wheel is about to lockup, port D "11" of the solenoid valve is opened by the
"depressurization" signal transmitted from the ABS ECU. When this occurs, the spool of the flow
control valve compresses the return spring and closes port B "9". Brake fluid that has entered
through port A "7" is restricted by the orifice "10" and the brake fluid is sent to the brake caliper
via port C "13" and port D "11", and the buffer chamber. As a result, the hydraulic pressure in the
brake caliper is reduced.
The brake fluid stored in the buffer chamber is pumped back to the brake master cylinder by the
fluid pressure pump linked to the pump motor.
