One of the very valuable things I learning in my first skim through the Bob Hoover sermon book is what the flare on the ends of the brake lines is called. I mentioned recently that the brake lines that I bought at the parts store were double-flared, but they were different than the lines in my beetle.
Well, hoover's sermons told me what I didn't know, which is what the VW's lines are called--they're called "bubble flared" lines. After I knew the name for them, I found this great page on "Tom's VW" with photos and explanations.
So now I know what to ask for at the parts store, which should get me the rest of the way. Off to shop.
