The invention provides an automatic brake air-releasing device. A solenoid valve is arranged in a bracket of a pipe coiling device; an air source for supplying air is connected with one end of the solenoid valve through a pipeline; a brake oil circuit of an automobile is connected with the other end of the solenoid valve through a hose of the pipe coiling device; the solenoid valve is connected with a control circuit for controlling the cycling switch of the solenoid valve; the control circuit is connected with an alternating current power supply; the control circuit is formed by serially connecting each of the switch and the solenoid valve with a circulation delayed relay and then connecting in parallel. The automatic brake air-releasing device has the beneficial effects that the air source and the solenoid valve are utilized to simulate an action of braking by foot, compressed air is adopted for pressurizing a booster pump, only one person is required for operating, the working efficiency is greatly increased, the operation is simple and easy, and the labor intensity is reduced. Under non-working state, the automatic brake air-releasing device can serve as a common pipe coiling device, the automatic brake air-releasing device is multifunctional, and the resource is saved.
