When the brakes are applied, the oil outlet opens and the oil inlet closes. Under the pressure of the piston of the pump body, the brake oil pipe is squeezed out of the oil pipe and flows to each brake cylinder for braking function. When releasing the brake pedal. The oil outlet in the brake master cylinder will close and the oil inlet will open, allowing the brake fluid to flow back from each brake cylinder to the brake master cylinder and return to its original state.

The air pump is driven by the engine to compress the air to high-pressure gas and store it in the air reservoir. One of the air reservoirs can be connected to the brake master cylinder through a pipeline. The brake master cylinder is divided into upper and lower air chambers. The upper air chamber controls the rear wheels, and the lower air chamber controls the front wheels. When the driver steps on the brake pedal, the upper air is opened first, and the high-pressure gas in the air reservoir is transmitted to the relay valve, pushing out the control piston of the relay valve. At this time, the gas in the other air reservoir can pass through the relay valve and the two The rear brake cylinder is switched on. The push rod of the brake cylinder is pushed forward, and the cam is rotated at an angle by adjusting the back. The cam is eccentric, and while rotating, it spreads the brake shoes and creates friction with the brake drum to achieve the braking effect.

When the upper chamber of the brake master cylinder opens, the lower chamber also opens. High-pressure gas enters the quick release valve and is then distributed to the brake cylinders of the two front wheels. The same goes for the rear wheels.

When the driver releases the brake pedal, the upper and lower air chambers close, and the pistons of the front wheel quick-in valve and the rear wheel relay valve return under the action of springs. The front and rear brake cylinders are connected to the atmosphere in the air chamber, the push rod returns, and braking is completed.

Generally, the rear wheels brake first, followed by the front wheels, which helps the driver control the direction.
