If you'd like to do this a bit more inexpensively, you might try taking the old lines to a hydraulic hose shop. These guys make stuff for heavy equipment and industry. I'm in a big construction area and also a big agricultrual area, so there are a number of such businesses. When my oil pressure line went, I got a replacement made up for about $6, hose and fittings. They did it while I waited. Never tried them for brake lines, but I wouldn't see a problem. Another alternative might be a brake/clutch shop. These used to be everywhere, not so much anymore now that relining brake shoes is less common. But we still have one in town.

As an alternative, there are cheaper places to order automotive braided stainless. But, some offer kits that you cut to length and then fit an end to. I'd be wary of those. Check the web.
