As the most important active safety system for automobiles, the design of braking systems has always been the most important part of the automotive design process. The purpose of this thesis is to target the 2.0L Camry sedan, and on the basis of drawing on domestic and foreign car brake system research results, using advanced design methods and analysis methods, first of all to understand the working principle of the car brake system, Then comprehensively analyze the structure and characteristics of various automobile braking systems, especially the design of the same type of mid-level car braking system, and carry out the overall design and structural selection of the brake system for the Camry car, and at the same time according to the relevant parameters of the 2.0L Camry car , Design calculation and strength check of its braking system. The braking system designed in this paper can be well adapted to the 2.0L Camry sedan, and at the same time meet the requirements of this type of vehicle for braking performance, manufacturing cost and many other aspects.
