18 / 30

What is the purpose of brake chambers?

To hold the brake pads

To transfer the force of compressed air to mechanical linkages

Yes

21 / 30

What is the purpose of a compressor?

25 / 30

What is referred to as a diaphragm?

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

A small port

None of these

A rubber seal that stops air from penetrating it

26 / 30

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