It HAD some kind of tape already on the brake line and it was covered by electrical tape! I have NO idea who or why... but, I didn't do it. Perhaps some other person feels like duct tape can solve most any problem, too!

My mechanical friend called and reported I need two front brake lines which he'll put on this week. He's very good and hopefully this will solve my brake problem until I get home. Then I'll see about a thorough replacement of old brake lines. Should I replace or have the master cylinder rebuilt? Or leave it alone until it goes bad?

I have learned more than I ever imagined there was to know about my brake system. Thanks to all who helped me here!! But, don't go away because if this fixes my brakes, I know, it won't be long before something else "brakes".
