▶ Pumping
When the cam pushes the left plunger during
motor operation, the system pressure is
generated in the left cylinder. At this time,
the right plunger is expanded by spring force
and the expanded volume of the right
cylinder draws the brake fluid.
▶ ECU (Including Solenoid Valves ? ESP
Equipped Model)
HECU controls the hydraulic valves by
supplying or cutting off the voltage to
solenoid valves depending on the wheel
speed and other information from wheel
speed sensors. The figure shown in left side
is for ESP ECU. There are two channels for
front wheels and one channel for rear
wheels. Each channel has one inlet and one
outlet valve, therefore, there are six solenoid
valves.
▶ ECU lower cover
The electrical components are weak to
moisture. To protect ECU, GoreTex-based
plate is used at ECU lower cover. The vent
hall (arrow) allows air to ventilate but does
not allow moisture to penetrate.
