I wouldn't have let them get away with that. Anyway, I would not pay for anything but the pads after i chewed some azz. I know that the pad material changed some time after 2000 because some rear brake pads were wearing out in as little as 5000 miles. Dealers were swapping out pads under warranty. I had 12,000 miles on mine when they were completely worn out. I don't know if you had the new version or not but I would expect that they were worn quit a bit. If you want to make a point about it, unless you signed an authorization to fix anything needing repair, they owe you $77.00, or at least the labor charge.
