With the rapid development of highway and the speed increased, and the increasing traffic density, CP, in order to ensure traffic safety, parking and reliable, the reliability of automotive brake systems become increasingly important. Only brake good, reliable car brake system in order to give full play to its dynamic performance. Disc brake, also known as disc brakes, which brake cooling fast, light weight, simple structure, easy adjustment, especially when the high temperature performance and high load, the braking effect of stability, but not afraid of mud invasion, and poor road conditions in winter Under the road, disc brake drum brake more easily than in a short period of time so that the car stopped. Some disc brake disk brake also opened a lot of holes to speed up ventilation, to improve braking efficiency. The general principles of the brake design, considering the braking performance, brake performance stability, ease of adjustment of brake clearance, the brake noise, the size and quality and design of this product and other factors. Synchronization involved in the design of the selection coefficient, selection of brake performance factors, the calculation of braking torque, and the main components of the brake selected for the final check on the calculation of brake design.
