The invention provides an automobile hydraulic brake device. According to the automobile hydraulic brake device, two oil outlets of a double-pipeline braking master pump are connected with oil inlets of two booster pumps respectively. Oil outlets of the two booster pumps are connected with a front-axle braking cylinder and a rear-axle braking cylinder respectively. Each booster pump comprises a pump body, an oil inflow screw, a different-diameter piston, a sealing ring, a spring, an oil seal and a pipe plug. During braking, the output oil pressure of the booster pumps is equal to the output oil pressure in the stage that braking clearance is eliminated; after the braking clearance is eliminated, input pressure is increased, the output oil pressure Po of the booster pumps is higher than the output oil pressure Pt, and pressure boosting braking is achieved.
