The present invention relates to the technical field of braking, and provides an axle brake module, an electronic brake system, a brake control method and an electronic device. The axle brake module includes: a relay piston for separating a valve chamber into a control chamber and a brake chamber, the control chamber being connected to a control port, and the brake chamber being connected to an exhaust port; a first check valve arranged in a first exhaust passage of the brake chamber that leads to the exhaust port; a second check valve arranged in a second exhaust passage of the relay piston that communicates the control chamber with the brake chamber; and an exhaust control solenoid valve connected to the control port. In a brake release state, air in the brake chamber pushes the first check valve to open the first exhaust passage, and pushes the second check valve to open the second exhaust passage, and the exhaust control solenoid valve is opened, wherein an opening pressure of the second check valve is less than an opening pressure of the first check valve. In the present invention, a waterproof function of the axle brake module is achieved by means of the first check valve; and exhaust of residual pressure from the valve chamber in the brake release state is achieved by means of the second check valve and the exhaust control solenoid valve.
