When the parking brake switch is pressed B position, the solenoid valve is energized and the
hydraulic oil controlled the pressure level by the cut-off valve enters the parking brake. It overcomes
the force of the spring and pushes the piston rod. This releases the brake.
Therefore, the hydraulic oil pressure is applied to the parking brake piston through the solenoid
valve and the parking brake is kept released.
