Thanks for actually explaining the terribly written booklet. I'm doing bus cert, and this stuff is very foreign to me.

Franklin Clinton

Thank you , You might save some lives with this video. At the very least it will save me a bad DOT inspection. I got my CDL in Ohio. We were only required to know the tolerances, not demonstrate it. My schooling ( Clark State) also didn't teach it. The six pack thing wasn't even taught ! I will use this knowledge from now on. Thanks again from a newbie.

Rosanna Sotomayor

I took a 16 hour air brake course last weekend and barely learned anything, had trouble staying awake as the teacher spoke. But after watching your videos all day I took the air brakes knowledge test and passed with ease (22 out of 25). Best CDL videos on the web.

Final Air Brake Quiz

Final Air Brake Quiz (Semi-Trailers Included)

 All vehicles designed to tow trailers with air brakes will have a tractor protection system which consists of the trailer air supply valve and the tractor protection valve. In this air brake course we show you how to test this system.Will this course work for my state or province?


All the test for the air brakes are the same throughout North America. Some of the numbers are slightly different, but the course provides a worksheet that will ensure that you have your numbers and tests in the correct order.

Air brakes are universal. For any air brake test, you are required to do a visual inspection of the air brake components on the outside of the vehicle, and test air brake adjustment using either the pry bar or the applied stroke method (mark & measure). The 5 in-cab checks are:

1) Governor (minimum & maximum settings)

2) Low-air warning

3) Application of emergency brakes

4) Compressor

5) Leak Test

A driving examiner is looking to see if you have a basic understanding of the air brake system, can check for adjustment, and conduct the in-cab checks.

This course teaches you the fundamentals of the air brakes, its many failsafes, how to check brake adjustment, and conduct the in-cab checks in a simple, easy to understand format.

And because road signs are universal, there are minor differences between states and countries.

 Will this course work if I'm already taking a CDL course?


° Most driving schools in North America are teaching a 40-year-old air brake course that is full of uneeded information

° Most air brake instructors confuse students by assuming they know about brakes and use complicated language to explain the topic

° Air brake boards and schematics further confuse students because you believe you must understand how to put the board together - YOU DON'T

° Many of the courses still teach such things as wig-wags, manual slack adjusters, and manual front wheel limiting valves as if these still exist - these components went the way of the dodo bird and the unicorn!
