The squealing is caused by the vibration of the metal backing of the pad. You can have plenty of material on the pad and you can have new rotors while still having squeal. Most shops put anti-squeal paste on the backing plate of the pad before installation - Mercedes are notorious for this issue. Go to the parts store, get some anti-squeal paste, remove pads, cover the metal backing plate entirely with a thin layer of the stuff, then put it back together.
