An airplane hydraulic brake system comprises a hydraulic brake valve, a liquid-controlled conversion valve, an electro-hydraulic servo valve, an anti-slide control box and a speed sensor. The liquid-controlled conversion valve is mounted on a downstream hydraulic pipeline of the hydraulic brake valve, the electro-hydraulic servo valve is mounted on a downstream hydraulic pipeline of the liquid-controlled conversion valve, an electrical interface of the electro-hydraulic servo valve is electrically connected with the anti-slide control box through a shielding insulation wire, an oil inlet of the electro-hydraulic servo valve is in pipeline connection with an oil outlet of the liquid-controlled conversion valve, a brake opening of the electro-hydraulic servo valve is in pipeline connection with an oil inlet of a brake device of a brake airplane wheel, and an oil returning opening of the electro-hydraulic servo valve is in pipeline connection with an airplane oil returning pipeline through a hydraulic filler neck and a guide pipe. The airplane hydraulic brake system can meet the ever-growing airplane take-off line brake requirement, is reasonable in structure, easy and convenient to implement, and beneficial for reducing of burdens of a driver, conforms to the man-machine engineering principle and meanwhile the accident potentials caused by false-operation switching on of a take-off line brake switch are eliminated.
