You can get a Class A CDL without air brakes - you'll just have a "no air brakes" restriction which prohibits you from operating a CMV equipped with air brakes. The vehicles you road test have to be commercial vehicles subject to FHWA regulations - recreational vehicles are exempt, so you cannot get a CDL with one.

slack adjuster is the adjuster on the brakes of vehicles with air brakes. these are used to adjust and take the slack out of the brakes caused by usual wear on the brakes
