The invention discloses a two-way hydraulic braking system. The two-way hydraulic braking system comprises two braking pedals, two braking oil pumps, two two-position three-way solenoid valves, and two oil storage pots. The two solenoid valves each include an interface a, an interface b and an interface c. When the two-way hydraulic braking system is powered on, the interfaces a and the interfacesb of the first solenoid valve and the second solenoid valve communicates with one another, the braking pedals and the braking oil pumps are connected with one another in a lined mode through piston rods, and the braking oil pumps communicate with the oil storage pots through oil pipes; the first braking pedal transmits data to the first solenoid valve through an electrical signal, the first brakeoil pump communicates with the interface b of the first solenoid valve and the interface c of the second solenoid valve through oil pipes, and the interface a of the first solenoid valve communicateswith a braking branch pump at the front axle end of a vehicle through an oil pipe; and the second braking pedal transmits data to the second solenoid valve through an electric signal, the second braking oil pump communicates with the interface b of the second solenoid valve and the interface c of the first solenoid valve through oil pipes correspondingly, and the interface a of the second solenoid valve communicates with a braking branch pump of the back axle end of the vehicle through an oil pipe. According to the two-way hydraulic braking system, braking of controlling one vehicle by two braking control mechanisms can be achieved.
