Most heavy truck brake systems use dual air for safety. and stop a dual air brake system has two sets of separate air brakes, using a single set of brake controls. Each system has its own air tanks, hoses, lines, etc. One system typically operates the regular brakes on rear axle. The other system operates the regular brakes on the front axle (and possibly one rear axle). Both systems supply air to the trailer (if any). The first system is called "primary" system. The other is called the "secondary" system. . Before driving a vehicle with a dual air system, allow time for the air compressor to build a minimum of 95-100 psi, in both primary and secondary systems. Watch the primary and secondary gauges of air (or needles, if the system has two needles in one indicator). Heed the warning light low air pressure and timbre. The light and warning bell should off when air pressure in both systems rises to a value set by the manufacturer. This value must be greater than 60 psi.

The light and warning buzzer should come on before the air pressure drops below 60 psi in either system. If this happens while driving, you should stop immediately and safely park the vehicle. If a system is low air pressure in either the front or rear brakes will not be fully operational. This means it will take longer to stop. Take the vehicle to a safe stop and have the air brake system inspected and repaired

For some this, different brake components in an air brake system work together to create and maintain a supply of compressed air, direct and control air flow and to transform the energy of air pressure in the force mechanical braking.
