I had a level 1 done in South Dakota almost a year ago. Had all disk brakes truck and trailer.
Although the inspector did slide around on his creeper front to back there wasn’t anything to check in regards to brakes. Unless something crazy they can see like cracked disks or pads falling out.
Told me that disc brakes make his life a lot easier since there’s nothing to measure.
Ended up with two stickers and a clean inspection report.
I’ll never buy anymore equipment with drum brakes..just a big pia.
