I bought my SS brake lines from a firm called
Classic Tube . They deal primarily in prebent applications; I'm not sure if they sell it in bulk or not.
I copped out and bought the prebent/preflared lines because I was doing the brake job in an unheated quonset hut in December, and didn't want to screw around with bending cold stainless steel tubing.
Classic Tube was very, VERY good to deal with. Aside from a shipping error -- which they fixed that same day -- I had no problems.
