Three (3) psi for single vehicles, four (4) psi for combination vehicles.
A two brake system, one operates the front brakes and one operates the back brakesWell it depends on what the previous answer is referring to; But when it comes to large class A commercial vehicles the following apply:A. A dual air brake system has two separate air brake systems which use a single set of brake controlsB. A dual air brake system has two separate air brake systems, the first system is called the primary system. The other is called the secondary system.C. A dual air brake system has two separate air brake systems, each system has its own air tanks, hoses, lines, etc..D. A dual air brake system has two separate air brake systems, both systems supply air to the trailer if there is one.If you see this question on a CDL written test and the answers are like these and then they have an E. All of the above, the answer is E.

Dual Air Brake Diagram
It will have a dual circuit application air brake system. Some motorhomes may use an air-over-hydraulic brake system.
A dual line system is a safety item. If a brake line/brake hose lets go you will still have brakes on one axle, you may not stop on a dime but it will stop you. A single line system will leave you with out any brakes at all if one brake line/hose lets go. American made cars have had a dual line systems since 1968.
A bicycle with a dual brake lever system offers the advantage of allowing the rider to control both the front and rear brakes separately. This can provide better braking power and control, especially in emergency situations or when riding on slippery surfaces.
A bicycle dual brake lever system offers the advantage of allowing the rider to control both the front and rear brakes with one hand, providing better braking efficiency and control. This can improve safety and handling, especially in emergency situations.
It's a dual circuit air brake system. Most use S-cam foundation brakes, although some use disc brakes or piston brakes.
If fluid is lost due to component failure, you will get total brake failure (loss of all braking except parking/emergency brake) on a single circuit system. A dual circuit system will only fail in one circuit, leaving the remaining circuit working. It is therefore safer.

A dual pivot caliper brake provides better braking power and modulation compared to a traditional single pivot caliper brake. This is because the dual pivot design allows for more even pressure distribution on the brake pads, resulting in improved braking performance and control.
The Tektro HDC 300 brake system features dual-piston calipers for improved braking power and control. It also has a lever reach adjustment for customizable lever positioning. The system is compatible with both mineral oil and DOT fluid. The brake pads are top-loading for easy replacement.
