Brake control system for vehicle sets greater main piston distance when all normally open solenoid valves are closed than piston distance when at least one solenoid valve is open

摘要

The system controls the distance of a main piston advanced by an automatic pressure application device when all normally open solenoid valves (PC1-PC4) are closed so that it is greater than the distance of the piston advanced by the pressure application device when at least one normally open solenoid valve is open.
