Abstract
A hydraulic braking system includes a base, which has an oil chamber and a connecting hole communicating with each other, a seat, which is provided in the oil chamber and has a receiving space communicating with the oil chamber and the connecting hole, a check valve movably provided in the receiving space and the connecting hole, and an elastic member. When one end of a connecting pipe which is connected to a brake actuator is inserted into the connecting hole to engage the base, the check valve is pushed inward to inject the hydraulic fluid in the oil chamber into the connecting pipe; when the connecting pipe is detached from the base, the check valve is pushed by the elastic member, and therefore returns to the original position. Whereby, the hydraulic fluid is prevented from leaking out.
