Front RH brake caliper• Since the cut valve 1 and the suction valve 1 are closed, the front RH brake caliper, master cylinder, and res- ervoir are blocked. This maintains fluid pressure applied on the front RH brake caliper. The pressurization for
the left caliper is controlled separately from the right caliper.
Front LH brake caliper
• Since the cut valve 2 and the suction valve 2 are clos ed, the front LH brake caliper, master cylinder, and res-
ervoir are blocked. This maintains fluid pressure app lied on the front LH brake caliper. The pressurization for
the right caliper is controlled separately from the left caliper.
Rear RH brake caliper
• Since the cut valve 2 and the suction valve 2 are clos ed, the rear RH brake caliper, master cylinder, and res-
ervoir are blocked. This maintains fluid pressure applied on the rear RH brake caliper. The pressurization for
the left caliper is controlled separately from the right caliper.
Rear LH brake caliper• Since the cut valve 1 and the suction valve 1 are closed, the rear LH brake caliper, master cylinder, and res- ervoir are blocked. This maintains fluid pressure app lied on the rear LH brake caliper. The pressurization for
the right caliper is controlled separately from the left caliper.

Front RH brake caliper• Since the suction valve 1 and the ABS OUT valve are closed and the cut valve 1 and the ABS IN valve are
open, the fluid pressure applied on the front RH brake ca liper is reduced by supplying the fluid pressure to
the master cylinder via the ABS IN valve and the cut valv e 1. The pressurization for the right caliper is con-
trolled separately from the left caliper.
Front LH brake caliper
• Since the suction valve 2 and the ABS OUT valve are closed and the cut valve 2 and the ABS IN valve are open, the fluid pressure applied on the front LH brake caliper is reduced by supplying the fluid pressure to
the master cylinder via the ABS IN valve and the cut valv e 2. The pressurization for the left caliper is con-
trolled separately from the right caliper.
Rear RH brake caliper
• Since the suction valve 2 and the ABS OUT valve are closed and the cut valve 2 and the ABS IN valve are open, the fluid pressure applied on the rear RH brake ca liper is reduced by supplying the fluid pressure to
the master cylinder via the ABS IN valve and the cut valv e 2. The pressurization for the right caliper is con-
trolled separately from the left caliper.
Rear LH brake caliper• Since the suction valve 1 and the ABS OUT valve are closed and the cut valve 1 and the ABS IN valve are open, the fluid pressure applied on the rear LH brake cali per is reduced by supplying the fluid pressure to the
master cylinder via the ABS IN valve and the cut valve 1. The pressurization for the left caliper is controlled

Component Parts and Function
VALVE OPERATION (ABS AND EBD FUNCTIONS)
The control unit built into the ABS act uator and electric unit (control unit) controls fluid pressure of the brake
calipers by operating each valve.
ABS IN valve Power supply is not supplied (open) Power supply is not supplied (open)
ABS OUT valve Power supply is not supplied (close) Power supply is not supplied (close)
Each brake caliper (fluid pressure) — Pressure decreases Name Not activated During pressure decreases
Component Function
Pump Returns the brake fluid reserved in reservoir to master cylinder by reducing pressure.
Motor Activates the pu mp according to signals from ABS actuator and el ectric unit (control unit).
Cut valve 1
Cut valve 2 Shuts off the ordinary brake line from master cylinder.
Suction valve 1
Suction valve 2 Supplies the brake fluid from master cylinder to the pump.
ABS IN valve Switches the fluid pressure line to increase or hold according to signals from control unit.
ABS OUT valve Switches the fluid pressure li ne to increase, hold or decrease according to si gnals from control unit.
Return check valve Returns the brake fluid from brake caliper to master cylinder by bypassing orifice of each valve when
brake is released.
Reservoir Temporarily reserves the brake fluid drained from brake caliper, so that pressure efficiently decreas-
es when decreasing pressure of brake caliper.
Pressure sensor Detects the brak e fluid pressure and transmits signal to ABS actuator and electric unit (control unit).

Front RH brake caliper
• Brake fluid is supplied to the front RH brake caliper from the master cylinder through the cut valve 1 and the
ABS IN valve. Since the suction valve 1 and the ABS OU T valve is closed, the fluid does not flow into the
reservoir. The amount of brake fluid supplied to the fr ont RH brake caliper from the master cylinder is con-
trolled according to time that the ABS IN valve is not energized (time that the ABS IN valve is open).
Front LH brake caliper• Brake fluid is supplied to the front LH brake caliper from the master cylinder through the cut valve 2 and the
ABS IN valve. Since the suction valve 2 and the ABS OU T valve is closed, the fluid does not flow into the
reservoir. The amount of brake fluid supplied to the fr ont LH brake caliper from the master cylinder is con-
