A two brake system, one operates the front brakes and one operates the back brakes

Well 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 controls

B. 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 system?

Not certain what your question is here. Every vehicle from 1976 - when FMVSS 121 became law - onwards will have a dual circuit application system, consisting of a primary air system and a secondary air system. Some systems retain a wet tank; some do not, and instead pipe air from the compressor directly into the primary and secondary supply tanks. Most often, the primary air system will be the system which actuates the brakes on the drive axle, as well as the trailer brakes when the foot pedal is applied. And the secondary circuit usually actuates the steer axle brakes, and the trailer brakes when the Johnson bar is used.

To turn off the dual zone auto air conditioning in a Peugeot 207, locate the air conditioning control panel. Press the "A/C" button to deactivate the air conditioning system.

This will allow the system to operate in a single-zone mode.
