Well, I bought new OEM Volve lines with fittings from www.borton.com. The Volvo line is cupric-steel and very flexible. It also comes pre-cut with fittings already installed, avoiding the ISO metric flare issues. Just let them know EXACTLY which lines you need and they'll ship. The price was reasonable considering I did not have to cut and flare them. They come coiled in a box.

Fishing them through the fender holes and then around the engine compartment required a little dexterity. Get a small tubing bender so you can make the sharp bends without kinking the tube. I found the cheapie Chinese-made one at my local discount auto supply to be easier to use and better than the more expensive Lisle tool.

I also replaced the flexible rubber lines at the same time, since those hose ends were corroded and shot too. I installed the stainless-covered IPD hoses since I had a set lying around, but they are not essential. Generic brake hoses are fine.

Finally, both front calipers were shot: dust seals torn and leaking, pistons a little corroded. I ended up getting rebuilds from FCPGroton which were great.

This job started out as new front pads and ended up as new front brake lines, brake hoses, calipers, and pads. Expect the worst.
