Component Parts And Function

Component Function
Pump Operates the pump drive according to signals from ABS actuator and electric unit (control unit) by the motor.
Motor Operates the motor drive according to signals from ABS actuator and electric unit (control unit).
Accumulator The accumulator accumulates brake fluid conveyed by the motor and pump.
ABS IN valve Increases, holds or decreases the fluid pressure of each caliper according to signals from ABS actuator and electric unit (control unit).
ABS OUT valve Increases, holds or decreases the fluid pressure of each caliper according to signals from ABS actuator and electric unit (control unit).
Cut valve 1
Cut valve 2
Shuts off the ordinary brake line from master cylinder to signals from ABS actuator and electric unit (control unit).
Suction valve 1 Suction valve 1 switches the brake line to convey accumulator pressure to the front system, according to a signal transmitted from the ABS actuator and electric unit (control unit).
Suction valve 2 Suction valve 2 releases accumulator pressure, according to a signal transmitted from the ABS actuator and electric unit (control unit).
Accumulator pressure sensor The accumulator pressure sensor detects brake fluid pressure accumulated in the accumulator and conveys the detected result to the ABS actuator and electric unit (control unit).
Master cylinder pressure sensor Detects the brake fluid pressure of master cylinder part and transmits a signal to ABS actuator and electric unit (control unit).
