The braking system mainly consists of four parts: energy supply device, control device, transmission device and brake. The energy supply device is responsible for providing the energy required for braking, including the master brake cylinder and air pressure source. The control device is mainly composed of the brake pedal, and the driver controls the size of the braking force by stepping on the brake pedal. The transmission device includes brake lines, brake master cylinders and wheel cylinders, etc., which are responsible for transmitting braking energy to the brake. The brake directly generates resistance to prevent the vehicle from moving or slow down its movement trend. There are mainly two types of drum brakes and disc brakes.
The drum brake generates braking force by rubbing the friction plate against the inner side of the rotating brake drum through a hydraulic device. The disc brake uses a hydraulic system to cause the friction plate on the brake caliper to rub against the brake disc that rotates with the wheel to brake. In addition, a complete braking system may also include additional devices such as braking force adjustment devices, alarm devices, and pressure protection devices.
The maintenance and care of the braking system is also very important. For example, the brake pads, as wear parts, need to be checked regularly and replaced in time when they are close to the wear limit. Brake fluid also needs to be replaced regularly due to its hygroscopic properties and its boiling point will decrease over time, ensuring that the fluid level does not fall below the lower limit mark on the brake fluid pot.
