Metal brake line flare fittings

[Craig D. Niederst]

While doing the RR caliper on my '92 100S last week, I noticed that the new caliper was ~180 degrees off when attached to the rubber brake line versus the old caliper. This meant I had to twist the rubber brake line somewhat in order to bolt the caliper into place. I attempted to remove the end of the rubber line attached to the metal brake line at the body to untwist the rubber line, but the connection is very rusty and would not budge (and is now badly stripped, even when using my flare wrench). I am going to replace the rubber caliper brake line and the short metal body brake line to correct the twisted rubber line problem. As you know, Audi does not sell individual metal brake lines, just lengths of line and the fittings. This means I need to make the correct flares on the end of the lines. Are these flares of the bubble variety or just a double flare? What is the best tool to make these flares? I see Sears sells a flaring tool, and was wondering if it would work. Any BTDTs appreciated. TIA.
