18 / 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

None of these

A rubber seal that stops air from penetrating it

A small port

19 / 30

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