Welcome to our air brake online training videos. These videos were created on our Class 3 single unit semi-truck with air brakes. Air brake endorsed vehicles vary in size, shape and class of licence required to operate it and could go from Class 1 all the way down to a Class 5. You will always need to customize your inspections to your specific vehicle, however these videos were created to compliment air brake endorsement training on a class 3 single unit air brake equipped vehicles in a driver training school.
