What are the reasons for low air pressure in the heavy-duty vehicle braking circuit?

[VanessaDella]

The reasons for low air pressure in the heavy-duty vehicle braking circuit include insufficient air supply from the brake valve, air leakage in the brake valve pipeline, air circuit blockage, and other faults. Function of the braking system: To forcibly decelerate or even stop a moving vehicle as required by the driver, to keep a stationary vehicle stable under various road conditions, and to maintain a stable speed for a vehicle moving downhill. Classification of the braking system: The braking system can be divided into the service braking system, parking braking system, emergency braking system, and auxiliary braking system. The braking system used to reduce the speed or even stop a moving vehicle is called the service braking system, while the braking system used to keep a stationary vehicle in place is called the parking braking system.
