The car will become more and more high-speed, braking system on the work of the increasing reliability requirements,Brake work of a reliable car,guarantee the safety of travelling,This shows that, The braking system design of practical significance. The braking system is one of important system of active safety. Based on the structural analysis and the design requirements of intermediate car’s braking system, a braking system design is performed in this thesis, according to the national and professional standards. First through analyzing the main parameters of the entire vehicle, the braking system design starts from determination of the structure scheme. SecondlyCalculating and determining the main dimension and structural type of the drum brake，brake master cylinder ans so on，Finally use of computer-aided design drawing draw the engineering drawings of the front and rear brakes, the master brake cylinder, the diagram of the brake pipelines. Furthermore, each target of the designed system is analyzed for checking whether it meets the requirements. some factors are considered in this thesis, such as simple structure, low costs, and environmental protection, etc. The result shows that the design is reasonable
