Maintenance of the vehicle brakes purpose is to restore the performance of the braking system. In order to meet the speed rail transport, satisfy the need of the heavy burden, ensure that the use of truck brakes state of technology ,to brake new materials, new technologies, new techniques and the development of the new structure. Railway vehicle braking device and its components must be rail vehicle brakes overhaul rules for testing and testing. The important components must to be used for measuring tool to testing, and gradually achieve automatic detection. Brakes and important parts to be used computer-control or NC-control equipment for testing. Wind-cylinder as the vehicle brakes as part of its main role is to be used for other brakes certificates wind. Wind-cylinder direct impact on the performance of the other brakes with brake function, for the wind-cylinder performance to go through stringent tests before being installed on the vehicle using the railway. In order to meet the wind-cylinder performance testing requirements, In this paper, micro-controlled areas were studied. Corresponding to design a Siemens S7-200 series PLC as the core of the wind-cylinder hydraulic pressure test system, VB6.0 use of software programming ,in the Windows environment to achieve the epistatic computer and PLC serial communications, and experts to control the entire testing process real-time monitoring. The device can be used in 40 L,
