HYDRAULIC UNIT (HU)
The hydraulic unit operates the solenoid valves based upon the signal which is output from the ABS control
unit. The brake fluid pressure is then adjusted accordingly. The hydraulic unit controls the front and rear
brake systems individually by operating separate components for the front and the rear, except for the pump
drive motor, which is shared by both systems.
