I replaced a couple of brake lines over the weekend using Summit's double flare tool ($39). Mikestang's suggestion to cut the line with a saw instead of a tubing cutter was HUGE! I took some emory paper to the end of the line to rough it up a bit, tightened it down evenly, reamed the end a bit, put a drop of
oil on the tool, and made sure I didn't over-tighten the flares. Perfect every time. Soooooooo much easier. I can't see how a $350 tool would make much difference.
What a great website!
