The photographs are on the driver's side (that's my thumb in there), but the passenger side had similar disintegration. I didn't observe any problems on the rear, but I didn't look closely either. I was able to compress the rear pistons by hand, but the fronts required a spreader and were very difficult even with the tool.
The borrowed calipers weren't nearly as bad, but they were only raced one weekend (3 sessions x 2 days). We didn't have time to photograph them after our last session at Sears Point.
