During the whole vehicle air brake check, in what general order should you proceed?

Pick an answer

1. Only the parking brake needs to be checked; the rest is optional
2. Check air buildup and warning devices first, then test the parking brake, then test the service brakes while moving slowly
3. There is no meaningful order; any sequence produces the same result, a point that's simple to get backwards with proceed
4. Release the parking brake first, then build air pressure afterward
