Does the hydroboost system use the same master cylinder as say a 3/4T truck...or is it different? Can you rebuild the m/c? I assume fluid is not supposed to be getting through here: http://community.webshots.com/photo/55167605/178635354jEHzUj Does this mean the master cylinder is junk? I pulled another one apart and there is a seal right below this that I think may be bad. Also, how can I get this piston out? The other one came shooting out as soon as I removed the snap ring, this one only comes to the point that you see it here, I can get it to shoot out all the way. I think that seal may be f'd up and jamming it up. Any ideas?
