when getting VB1 and V08 done, dealer (of course) “found” other ways to liberate my money from me. Two items at least semi -legitimate but for the second time (first after going in Dec. to diagnose leaking cooler) they said I needed brakes. So befor I took it in this time I pulled left front and rear tires and measured pad thickness. About 6 mm (couldn’t get calipers directly on pad but close). The service form shows spec at 3 mm. I told the service advisor I measured 6 mm so one of us is wrong. My suspicion is that the service tech had a quick look, figured they were close enough, and to get the form cell to go red, simply entered 3 mm to make it pop red. I have 63,000 miles on the truck but am not original owner. I suspect they are the original pads. Earlier they wanted to replace an AC evaporator saying it was clogged. Nothing wrong with it. Needless to say it is only going there for warranty work and I need to find an independent diesel mechanic. Sure wish dealers were a little bit honest, but I suspect they prey on a generally mechanically illiterate general public.
