Brake failure — Arizona Permit Test
Brake failure on the Arizona permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
If brakes fail in a vehicle without anti-lock brakes, pump the brakes rapidly to try to build up enough pressure to stop.
A fast pumping action can push enough fluid through to make the brakes grab again.
Pump the brakes rapidly. This may build up enough pressure to stop your vehicle.
If pumping the brakes does not work, slowly apply the parking brake.
The parking brake works apart from the main brakes. Pulling it slowly keeps the rear wheels from locking up.
If pumping the brakes does not work, slowly apply the parking brake.
When your brakes fail, shift to a lower gear and look for a safe place to stop.
A lower gear lets the engine hold the car back, slowing it even when the brakes will not.
Shift to lower gear and look for a safe place to stop.
On the test
If the brakes fail in a car without anti-lock brakes, what should you try first?
Pump the brakes rapidly. A fast pumping action can push enough fluid through to make the brakes grab again. Arizona Driver License Manual and Customer Service Guide, p.69: “Pump the brakes rapidly. This may build up enough pressure to stop your vehicle.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
