Perhaps it wasn’t even the mechanic that safetied the van who last put the wheels on.Drum brakes = yes. Disk brakes = maybe, if checking for more than wear, like stuck pins or torn boots. Uneven wear, if detected, would lead some Mechanics to look further. Some may ever create a fuss about rust on the brake lines, it all depends on how concerned the Mechanic is about safety or being audited. Front wheels don't come off very often, more like never, in my experience with safety inspections.
Vehicles, that have passed safety inspection at one shop, say a Dealership, have been looked at by another shop, for whatever reason, and written up or rejected because of a perceived safety problem. The vehicle Owner, of course, gets very upset and may even go public/legal.
