To put things in perspective, on my 95 E320 the pad thickness is 11 mm when new and 2.5 mm when the wear sensor makes contact (23% of pad thickness remaining). Don't wait too long though. You certainly don't want metal-to-metal wear on the rotors. Two mm pad thickness is the specified discard thickness.
