I am the new proud owner of a '51 3600 and am having difficulties with my master cylinder rebuild, I put it all together and test the new pump (not hooked up with only fluid in the resivour and cannot get it to pump. Any ideas? I have gone over the shop manual and am still having trouble with it, and I just don't want to break down and buy a $100 new cylinder if I dont have too. None of the passages are blocked so I'm hoping it's just my crappy rebuilding skills. Thanks for the inputs!
