What types of braking systems are there?

There are these types of braking systems:

(1) According to functions: service braking system, parking braking system, emergency braking system and auxiliary braking system. ① The service braking system is operated by the driver with his feet, so it is also called foot braking system. Its function is to slow down the moving car or stop it in the shortest distance. ② The parking brake system is operated by the driver's hand, so I also call it the handbrake system. Its function is to keep cars that have been parked on various roads in place. (3) The emergency braking system is an independent pipeline control wheel braking system as a backup system. Its function is to ensure that the car can still slow down or stop when the braking system fails. In the braking laws and regulations of many countries, emergency braking system is also necessary for automobiles. (4) The auxiliary braking system is used for automobiles and some special automobiles that often drive in mountainous areas, so as to improve the driving safety, reduce the performance degradation of the braking system and brake wear, and stabilize the speed when going downhill. Among them, engine exhaust braking is the most widely used.

(2) According to the braking energy transmission mode: mechanical, hydraulic, pneumatic, electromagnetic and combined.

(3) According to the number of circuits: single-circuit braking system and double-circuit braking system.

(4) According to energy sources: hand braking system, dynamic braking system and servo braking system. ① Hand braking system: a braking system with the driver's body as the only braking energy source. (2) Dynamic braking system (3) Servo braking system is a braking system that completely relies on the power of the engine to convert it into potential energy in the form of air pressure or hydraulic pressure. A braking system that uses both human power and engine power for braking.
