Rotated tires today looks like the front pads are wearing down not on the squeeler yet, but I can't see how much is left before they are on the squeeler. Might have another 5k left only 34K on the odometer. Is there another way to determine whats left on the pads without removing the caliper? Should I wait till I hear the squeeler rubing? When I replace the front pads, I am not going to turn the rotors, is there somthing else I need to pay attention too. Thanks Tom
