I use a real nice little hand held bender that works great. It's a
Rigid #36117 and it's funny I saw this post as I'm finishing off my brake lines as I type this from the shop. Thought I had them nipped in the butt yesterday but found a leak today and had to bend up a new piece of stainless tubing because one of the ends didn't flare to well. Click that link above to see the tool. Works great!
