The main innovation in the braking system presented for patent protection is that it avoids the use of a main brake valve, as well as the other cocks and valves used presently in the air brakes. The pressure in the brake chambers is regulated hydraulically or electrically at the input of each brake chamber individually. This minimizes, to the extent possible, the delay in the execution of the brake commands given by the driver. ABS control will also be individual for each wheel and will work several times faster and more accurately. Overall, the system will use much fewer air ducts, will be simpler and more secure. The diagnostics will be much faster and easier. For reequipping the vehicles with the presented braking system, no changes in their design are required.
