Brake Disc Caliper problems of the 2007 GMC Yukon

Driver side front rotor outer surface has full metal to metal contact with zero brake pad material and had to be pried out. Driver side front rotor inner has uneven partial surface contact with rotor and is jammed in the carrier (unable to remove by hand, had to be hammered out of the carrier). Passenger side brake rotor outer has perfect surface but brake pad looked brand new. . . No wear on it and is jammed in the carrier. Passenger side brake rotor inner surface has partial contact with brake pad. . . Heavy thick rusty ridge formed and brake pad showed ridge impression on it. Customer said the brake was done by dealer two years ago. The main culprit is the brake pads are jammed in the carrier because the brake pad backing plate is too long to insert or to move freely. There is some kind of design flaw/specification problem. The driver side required much more shortening of the new brake pad backing plate than the passenger side. Brake pad tab width was perfect and moves easily with no play. It is only the length of the brake pad tabs are the issues. I am not sure if the brake pad/caliper carrier is at fault. . . Possibility of bending or twisting that may cause the issue of brake pad being jammed, or too long to insert. It is such a strong metal that there is no way any human can physically bend it nor simply dropping it. It would take a severe force to actually bend the carrier such as the vehicle itself under repeated braking. I think this is the most plausible reason for this situation. New brake pads has same problem. . . The length of the backing plate tabs are too long to insert into carrier on driver side and they do fit too tight in passenger side carrier. We had to shorten the brake pad tabs to allow the pads to move smoothly in the carrier.
