Reply to "removal of second stock rear caliper?"

The caliper that seemed to be binding the most was the right rear, so I took it apart. Attached is a photo of the WORST area of corrosion on the piston.
Actually it was just discoloration that wiped off the entire piston literally with 30 seconds of light wiping.
There was some black granular mud stuff in the caliper bore that just wiped away - there was no rust beneath it.
The reservoir is made of metal and there is absolutely no sign of corrosion in it or the fluid in it, the latter being crystal clear.

I took off the forward caliper on that side, turned it upside down, and bled the fluid out using a suction device. It was crystal clear without any sign of rust. So it seems there was no water in that caliper.
