I don't think it's a stuck piston. I had to use a c-clamp on both to move them back out of the way to flip up the caliper. Would it be ok if I pressed on the brake while the caliper was flipped up and someone was watching the pistons? Or is there a possibility of pushing the pistons out too far if I were to do that (without having the pads to restrict their travel)?
