There is a brake cylinder. The brake cylinder pushes the brake pad to contact the brake disc to generate braking force. There is only one caliper per wheel brake. However, the number of pistons on the caliper is different, and the calipers are divided into floating and fixed. The floating caliper can move axially along the brake disc, and the sub-pump piston is arranged on one side, and the normal one has only one sub-pump piston. The number of opposed caliper pistons is even. In general, the greater the number of pistons, the greater the braking force and the higher the caliper.

Many high-end cars begin to study the automatic braking system for the driver's own driving skills and reaction characteristics. The working principle of the general automatic braking system The main reason is to monitor the road ahead in real time by means of sensors installed in the front of the vehicle. When there is an obstacle in front and a collision may occur, the system will perform an audible and visual alarm to alert the driver to brake or automatically perform emergency braking.

随着自动刹车系统的普及，对应的卡钳结构进行了调整，原先卡钳内的活塞，螺栓，螺母结构不再适用，需要新的匹配结构。With the popularity of the automatic brake system, the corresponding caliper structure has been adjusted. The piston, bolt and nut structures in the original caliper are no longer applicable and require a new matching structure.
