Manually lubricated

Not lubricated

14 / 30

What is referred to as compressed air?

16 / 30

The governor must take the compressor out of its pumping stage when system air pressure reaches...

80-90 psi

150-170 psi

90-110 psi

120-145 psi

17 / 30

All compressors run continuously...

When the engine is running

When the engine is off

When the generator is running

All of these

18 / 30

How is heat generated by the brakes dissipated?

It's absorbed into the tires

By passing it off into the atmosphere

It's absorbed through the pads

It's pushed into the air lines

19 / 30

What is the purpose of brake shoes and drums or brake rotors and pads?

To house the braking components

To create the friction needed to stop the vehicle

To prepare the vehicle to stop

All of these

20 / 30

What happens when air pressure is released from the service-brake chamber?

The spring brakes activate

None of these

The wheels stop turning

The return spring returns the diaphragm and push rod to their released positions

21 / 30

Each reservoir is equipped with a drain valve called...

A release valve

A tank valve

A draincock

A push drain

22 / 30

Will the reservoirs be able to store a sufficient volume of air to allow several brake applications if the engine stops or the compressor fails?

Depending on the number of reservoirs

Yes

Depending on the size of the reservoirs

23 / 30

When you press down on the foot valve, air pressure enters the pressure side of the brake chamber through what?

The exhaust port

The inlet port

The slack adjuster

The spring valve

24 / 30

What's another name for the floor-mounted brake pedal?

Pedal valve
