The invention provides a vehicle friction plate dragging torque test method and device, a distribution diagram test method and devices. The vehicle friction plate dragging torque test method comprises the following steps of: controlling wheels to rotate at a preset rotating speed; acquiring a corresponding first resistance moment when the wheels rotate at the preset rotating speed in the state that the friction plate of the vehicle is not detached, and acquiring a corresponding second resistance moment when the wheels rotate at the preset rotating speed in the state that the friction plate is detached; and calculating the difference value between the first resistance moment and the second resistance moment to obtain the dragging moment of the friction plate. According to the scheme, the resistance moment of the brake friction plate to the brake disc is accurately reflected, a resistance evaluation system of a brake system is conveniently perfected, and development of a low-resistance brake friction plate is f
