Unfortunately, you must pay for your CDL air brake test. You can visit www.cristcdl.com/otc/ab4/ to read more about it.
This isn't something you'd do on your own. I would search for a professional in your area who does CDL brake tests.
You can get a free CDL air break practice test at www.testquestionsandanswers.com/cdl/air-brakes-test.html You could also try calling around local truck stops for help.
You can prepare for the written test for free at a site like: http://www.truckercountry.com/cdl-air-brakes-test.html . For the practical portion, not really, since you need a commercial vehicle to do so.

One can expect to find a free CDL practice test by going into the local licensing office and asking a representative to have a practice test to prepare for the CDL exam.
Yes.
When you got your CDL did you take the road test in a air brake equipped vehicle? If you did not then you have to retest to add air brakes. Not the whole test just the air brake portion both written and pre-trip portion of road test.
All the answers to the questions on the written test are provided at no charge in the CDL handbook. All you have to do is study it.
Take the written air brakes test, and perform a road test in a combination requiring a Class A CDL which is equipped with air brakes.
There is no designated time in which to take the Free CDL tests. The free CDL testing is offered online, along with practice questions in which to test your ability.
In order to find information on doing a CDL practice test you can contact your local DMV, which sells CDL pratice test. They also offer a free shorter practice test on the DMV website.
