Yes

15 / 30

What is referred to as compressed air?

When air is pushed through smaller air lines

When air is pushed into a smaller space

When air is released into the atmosphere

16 / 30

What is referred to as a diaphragm?

A small port

None of these

A heavy rubber partition in the brake chamber that activates the brakes when air is forced against it

A rubber seal that stops air from penetrating it

17 / 30

10-15 psi

30-35 psi

20-25 psi

40-45 psi

18 / 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

19 / 30

The maximum air pressure available for brake applications depends on what?

The size of the reservoir

20 / 30

What is the purpose of a foot valve?
