Oh yeah, I definatlely used pressure to try to get the piston back. I need to try what you said and open the nipple but I wanted to know if there was something I was missing before trying something that might let air in the lines, because it looks like it would be a pain in the ass to bleed the brakes on this bike. I will give that a try tomorrow, but it still seems that it shouldn't have that much resistance. The back wheel is still really hard to turn and the brake lever is fully retracted. Thanks for the help.
