The invention provides a double-pull-rod center valve type hydraulic brake master cylinder which comprises a cylinder body, a primary piston, a secondary piston, a center valve type device and the like. The center valve type device has the advantages that the center valve type device is high in response speed, the flow direction of brake fluid can be rapidly switched, and the instant braking requirement is met; all parts are tightly matched, stability is good, and braking force is uniform and stable; the sealing spring has small elasticity to avoid damage to the fourth sealing ring and ensure the system reliability; the spring seat and the valve seat are special in structure, so that stable work of the return spring and the pull rod and balanced circulation of brake fluid are facilitated; the connection of the primary piston and the push rod and the annular groove design of the secondary piston provide guarantee for the normal operation of the braking system. In conclusion, the patent technology effectively improves the performance and reliability of the hydraulic brake master cylinder, and provides important guarantee for safe driving of an automobile.
