4 psi in one minute.
When performing a static leakage test on a double combination vehicle with air brakes, the leakage rate should be no more than 3 psi in one minute. If air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.
22 . If the safety relief valve in an air brake system is releasing air:
The safety relief valve in an air brake system releases air if necessary to prevent pressure in the system from becoming too high. If the valve starts releasing air, there is something wrong. Have a mechanic fix the problem.
23 . A dual air brake system:
Has two separate air brake systems, but uses a single set of controls.
A dual air brake system has two separate air brake systems that use a single set of brake controls. One system typically operates the regular brakes on the rear axle or axles. The other system operates the regular brakes on the front axle.
24 . Why do you need to drain air tanks regularly?
To remove bad air from the tanks
Compressed air in an air brake system usually contains a certain amount of water and compressor oil. The water and oil can damage the brakes if left to accumulate in the system. Tanks must be drained regularly to remove this build-up.
25 . How many air storage tanks are used in an air brake system?
The number varies.
Air storage tanks are used to hold compressed air. The number and size of air tanks in an air brake system varies among vehicles.

The Class B CDL skills assessment in Florida includes three parts: a pre-trip inspection, a basic vehicle control test, and an on-road driving test.
