Turn-off pressure

Put-out pressure

Put-in pressure

23 / 30

The actual air brake system pressure range must never be higher than what?

145 psi

130 psi

125 psi

110 psi

24 / 30

Which are not some of the problems that can occur from the wet tank?

Moisture in the brake system remains warm and stops freezing in cold temperatures

The collected moisture and oil mixture can form a sludge that can pass from the tank into other components of the air brake system

Too much moisture and oil collecting in the air tanks can reduce the volume of air and may cause brake failure

The mixture of moisture and oil can become corrosive and damage the air tank and other system components

25 / 30

Why should the supply tank always be drained first?

It doesn't matter which tank is drained first

To prevent accumulated moisture flowing into the next tank being drained

It's the biggest tank

It's the first and easiest tank to reach

26 / 30

Is it unsafe to drive a vehicle when the air pressure is outside the normal operating range?

Only at highway speeds
