Thanks for the tips. There's got to be some way to turn the pistons without removing them completely. The last thing I want to do is have to blow air in there and then have to flush them out. I'm going to try extending the pistons a little with the pads out (and a block of wood in there), then putting a hose clamp around them with a shop rag or paper towel underneath (to prevent marring).
