Operating
Normal braking or pressure increase mode
• During normal braking or pressure increase mode the inlet and outlet solenoid valves are not energized: the
inlet solenoid valve is open and the outlet solenoid valve is closed. Brake fluid pressure from the master
cylinder flows through the inlet solenoid valve and is transmitted to the caliper piston. At this time, the pump
motor does not operate. (Description for single front wheel only)
