I've got my new brake lines installed. . . however, I went to start bleeding the system and a couple of the new lines are leaking from where the 1/4" line goes into the fitting. I removed one of the lines and compared the double flares I did and they look identical to the original GM lines. Why would they be leaking? I read some other threads talking about 37* and 45* flares Are they talking about degrees? I used a Craftsman flare kit.
