When rear RH wheel caliper pressure holds
• Motor is activated. Brake fluid is pressurized by pump and is sent to primary line through cut valve 1. At the
same time, because ABS IN valve and ABS OUT vale are closed, fluid pressure holds.
When rear LH wheel caliper pressure holds
• Motor is activated. Brake fluid is pressurized by pump and is sent to secondary line through cut valve 2. At
the same time, because ABS IN valve and ABS OUT vale are closed, fluid pressure holds.
ABS is in operation (when pressure decreases)
When front RH wheel caliper pressure decreases
• Being supplied to reservoir through ABS OUT valve, the fluid pressure of brake caliper is decreased.
When front LH wheel caliper pressure decreases
• Being supplied to reservoir through ABS OUT valve, the fluid pressure of brake caliper is decreased.
When rear RH wheel caliper pressure decreases
• Being supplied to reservoir through ABS OUT valve, the fluid pressure of brake caliper is decreased.
When rear LH wheel caliper pressure decreases
• Being supplied to reservoir through ABS OUT valve, the fluid pressure of brake caliper is decreased.

SYSTEM
VALVE OPERATION (OTHER THAN ABS AND EBD)
Each valve is operated and fluid pressure of brake caliper is controlled.
NOTE:
There is no operation to hold and increase pressure for functions other than ABS and EBD.
When Pressure Increases
Component
FUNCTION
Reservoir
Temporarily reserves the brake fluid drained from brake caliper, so that pressure efficiently decreas-
es when decreasing pressure of brake caliper.
Pump
Returns the brake fluid reserved in reservoir to master cylinder by reducing pressure.
Motor
Drives the pump according to signals from control unit.
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 line to increase, hold or decrease according to signals 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.
Cut valve 1
Cut valve 2
Performs the duty control of fluid pressure increased by pump according to signals from control unit.
Pressure Sensor
Detects the brake pedal operation amount.

When front RH wheel caliper pressure increases
• Motor is activated. Brake fluid from pump is supplied to front RH wheel caliper through ABS IN valve. For
other wheel, ABS IN valve is closed and brakes fluid is not supplied to caliper.
When front LH wheel caliper pressure increases
• Motor is activated. Brake fluid from pump is supplied to front LH wheel caliper through ABS IN valve. For
other wheel, ABS IN valve is closed and brakes fluid is not supplied to caliper.
When rear RH wheel caliper pressure increases
• Motor is activated. Brake fluid from pump is supplied to rear RH wheel caliper through ABS IN valve. For
other wheel, ABS IN valve is closed and brakes fluid is not supplied to caliper.
When rear LH wheel caliper pressure increases
• Motor is activated. Brake fluid from pump is supplied to rear LH wheel caliper through ABS IN valve. For
other wheel, ABS IN valve is closed and brakes fluid is not supplied to caliper.
