Ok, I replaced the master cylinder and rebled the lines. All is working great. Thanks all for your help. However, one more question.
I noticed with old master cylinder and new cylinder the metal plug (cap) on top doesn't appear to be sealed. When I was bleeding the cylinder on new one, I held upside down and small fluid leaked out. This is the case for new one and old one. So when I was completed, I put a couple layers of Teflon tap on cap to seal it off. My mind of thinking says it needs to be completely air tight. Then why wouldn't the cap have some sort of gasket?
