Which statement is false? Air brakes are different because...

Vehicle reaction feels different

They require less driver involvement

There are more gauges and controls

The pedals feel different

17 / 30

What does the supply circuit do?

Provides information for the employer to use for training

Adjust the tire pressure

None of the above

Compresses and cleans the air, maintains consistent air pressure

18 / 30

When does contamination drain most effectively?

Once the park brakes are applied

It doesn't

After the tanks are empty

Once more air is forced through the system

19 / 30

Which statement is incorrect? Air brakes are different because...

The require more driver involvement to make sure that the system is operating safely

Vehicle reaction is different

There are less gauges and controls

The pedals feel different

20 / 30

How do you monitor the air pressure?

Gauges on the dashboard

Testing the brakes on occasion

None of the above

You have to manually check the tanks

21 / 30

How often should you drain the supply tanks?

Never

Only if the gauges show a problem

Once you notice contamination

During pre-trip inspections, enroute inspections and fueling

22 / 30

None of the above

The purge tank

The main tank

26 / 30

What's the purpose of safety valves?

Just a safety thing

Allows the brake hoses to be replaced easily

Protects the system from being over-pressurized

Allows the cylinders to be cleaned

27 / 30

What do Inline Alcohol Injectors do?

Helps to fill the compressors

Adds vaporized air line antifreeze to the air supply

Cleans the air hoses

Polishes the compressors

28 / 30

Where is the driver when control and quick release valves exhaust forcefully?

Inside the cab

Outside the vehicle

Doing routine maintenance

Under the hood

29 / 30

Do you need to wear any personal protective equipment when servicing air system work?

Yes
