2000 Ford Taurus just did the front discs and new pads. Existing pads had only about 28,000 miles. I have never seen the wear pattern as this time. I have had pads that wear unevenly, front to back, etc. The caliper is one cylinder from the inner side. In the past when I have had a sticky caliper the overwhelming wear has been on the inboard pad. I always remove the caliper pins, clean, then lubricate. wire brush the caliper as well. This time the driver's side pads were in good shape, quite a bit of wear left, rotor in good shape. Passenger side the inner pad was identical to the driver's side, lots of pad and wear, inside surface of the rotor fine, but the outer pad was down to the metal backing, severely scoring the outer surface of rotor. What would cause the outer passenger side pad to wear so severely and damage only the outer side of the rotor? In the past when I had a sticky rotor the more severely worn pad was on the inside, next to the piston. I wonder if possible pad defect, or is there some mechanical problem that would explain this?
