Especially when the system of hydraulic brake realized the adjustment to the press, traveling schedule and speed, the equipment not only completes the processing of the complex and asymmetrical work-pieces, and moreover the rate of its rejection is very low, comparing with the machine-finishing system, which has the enormous superiority. In the resent years, with the development of the microelectronic and hydraulic technology, the hydraulic brake has the further development, whose high-tech content is increasing, and the numerous types had controlled by the CNC or PC machine which increases the processing quality and the productivity.</p><p>At first, this paper as a whole carries the design and the essential examination on the hydraulic brake. Second, it carries on the preliminary design to the entire hydraulic control system, and the computation to the main parameters of its master cylinder, then analyses the obtained results. Thus it enables the master cylinder of the hydraulic brake to satisfy the request of the product technique, and enhances its standard overall, which causes its design level on a new stair. This design is mainly in the view of different technological requests, according to the main structures of the equipment, the force sizes of the master cylinder and the request of the working conditions to choose the kinds of every part. At the same time, it involves the choices of hydraulic cylinder&#39;s support pattern and piston and active crossbeam connection pattern and guide sleeve and seal, enhancing the hydraulic press whole use intensity and the life and causing the craft precision to conform to the request goal productions.</p><p>Keywords: The hydraulic brake; the hydraulic controlling system; master
