Brake lines

I am on my second set of stainless steel Inline Tubes (IT) brake lines on my MC. The connection at the MC for the rear brakes will not seat - it weeps.

I attached the lines according to IT’s instructions, but no help. That’s when I broke down and bought another set - same damn problem.

Then this past weekend I watched “Gearz,” and he was making brake lines and he commented that you should use nicopp or steel, but not stainless steel. The reason? Stainless steel cannot be double flared- only single flared, and that tends to crack, or not seat, and will probably leak.

Tomorrow I will try to make a nicopp line, double flare it and see if that leaks.
