PROBLEM TO BE SOLVED: To provide an inexpensive brake device for combined operation allowing a brake instruction transmitting time to be shortened even in the combined operation of an air car and an electric car. SOLUTION: In an electric car side re-reader 10, a brake instruction for the electric car is converted into an electric signal by using a specified conversion factor, and transmitted to an air car side re-reader 9 through an electric cable 11a. The air car side re-reader 9 converts the received electric signal inversely to a target brake pressure value by using a specified conversion factor. Then, according to an automatic electromagnetic brake system, a solenoid supply and exhaust valve 8 is energized/deenergized so that an actual BP pressure follows the target brake pressure value. Also when the brake instruction is transmitted from the air car to the electric car, the actual BP pressure is converted to an electric signal by using the conversion factor, and the electric signal is transmitted to an electric car side via an electric cable 12a.
