If your vehicle has air brakes, the air compressor drive belt should be checked before each drive. Check the tightness of the belt and verify that it is in good condition.

2 . During an applied leakage test, what is the maximum leakage rate that is safe for a single vehicle with air brakes?

It is important to know the maximum air loss rate that is safe for your specific vehicle. A single vehicle with air brakes should have a leakage rate no higher than 3 psi in a minute during an applied leakage test.

3 . Air tank drains:

4 . What is removed when an air tank is drained?

In an air brake system, air tanks have drains to remove accumulations of water and compressor oil. Allowing water and oil to accumulate in the system could cause damage to the brakes.

5 . What kind of brakes do most newer heavy-duty trucks use?
