It adopts a double-push rod design, that is, two push rods act on the friction plate at the same time, making the overall force on the friction plate more uniform and reducing the pressure per unit area. When the driver steps on the brake pedal, the gas in the brake air circuit system is pressurized and transmitted to the brake.
