Yikes! I'm looking at the contact area (or rather the lack of) on those pads. For maximum braking efficiency the pads need to make full contact with the rim - not just on one corner
That was not the wear pattern! I was in the process of sanding the glaze off and evening up the pads. Once I saw the metal. I just sanded that area to clean it up for a picture. The corner was all that was left. I decided to toss the pads so I really didn't care how flat I made the braking surface.
