The paper mainly discusses the layout and composition, pipeline design and installation, chassis assembly and commissioning process and commissioning of quality control, as well as chassis and body engaging process. The bus chassis technology is the key to vehicle technology. Whether the brake lines are good or bad, directly impacts on passenger gas and brake performance. The model is a four-circuitpneumatic brake system, whose reasonable arrangement of piping is mainly based on the theory and design of the system, and finally through the system performance analysis, maximizing its life and improve the braking performance and stability. Chassis assembly, commissioning process and commissioning of quality control, are mainly to the air brake system check, brake system road test process, and the service brake and axle load distribution check, to check the braking performance. Keywords: chassis brake lines, the end of the skeleton, chassis assembly, brake pedal, service brake. Bottom skeleton which is mainly based on customer requirements, operating environment, and the standard paragraph or table skeleton chassis and the middle of the chassis skeleton is made to improve the design, assembly to meet the skeleton design specifications premise original bottom skeleton to achieve optimization under frame purpose. 【Key words】 chassis brake lines ; the end of the skeleton ;chassis assembly ; b
