Need help...wearing out one side of brake pads more than the other

Yup, I agree...remove your calipers and clean them up. Take out the spring plates and get all that dust buildup out from under them. Did you have a hard time getting your old pads out? Did you have a harder time getting the new ones in?? If so, the spring plates may be the culprit.
Mine get so bad the pads wind up riding "up" in the caliper slots to where pad material is hanging OVER the edge of the rotor...I notice this about every three pad sets.
FWIW, it's a bee-otch getting those springplates out - the screws are at an angle, difficult to get at and they're in there good!

Mark,
I was tryong to say what the others did. I did not have any pics though.
Where the leading edge and the trailing edge of the pads are in the calipers gets corroded or otherwise mucked up. When the pistons push the pads towrd the rotor, the edge of the pads move in towrod the rotor but no freely back due to this crud. I do ususally hit the edges of the pad's backing plate too, but mostly it is the part of the caliper where the pad backing plate slides toward and away form the rotor that causes the problem.
If you have ever used a rubber mallet to force new pads in, that is the culprit.
Your problem sounds different though since there is no problem removing or dropping new pads in.

One more possibility that has not been mentioned - uneven cooling. If you are using brake ducts to funnel air to the rotor, check to see if the hose on one side has a hole or perhaps have come loose, allowing air to escape. If one side is getting air and the other isn't, one side will got hotter than the other and wear faster.
