The brake cam

The return spring

The slack adjuster

The brake camshaft

17 / 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 size of the reservoirs

Yes

Depending on the number of reservoirs

18 / 30

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

All of these

To house the braking components

19 / 30

What is the purpose of a foot valve?

To draw compressed air from reservoirs when it is needed for braking

To release the trailer brakes

20 / 30

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