No SS lines as I was considering, but they now have PVC coated steel lines. I haven't done brake lines since many years- never seen these. I'm concerned the coating will crack when bent. Does anyone have any firsthand experience with these? | | | | Joined: May 2005 Posts: 8,877 . | . Joined: May 2005 Posts: 8,877 | Look into nickel copper brake lines, very easy to work with and at least as corrosion resistant as Stainless if not more so. eBay has good prices lately but also available from local auto parts store. An example part number is CNC-325 for 25' of 3/16" line. | | | | Joined: May 2005 Posts: 1,624 Shop Shark | Shop Shark Joined: May 2005 Posts: 1,624 | Edit: Grigg beat me to it but he and I are on the same page.
May I offer a different solution? All my brake lines are made up with copper/nickle tubing. 90% copper/10% nickle. It has a 'trade name' but I don't remember it. The tubing is certified by everyone for brake line use. I understand that most of the high price European cars use it, especially Sweden where corrosion from salt is a problem. It's very easy to work with. Your tubing bender and flaring tool will love you for it. The double flairs used on brake lines made with SST will ruin cheap to mid-priced flaring tools. More pricey than carbon steel tubing but well worth it in my opinion.

One of the reps brought me a sample piece of 3/16" that was coiled around a 1/2 id. I've also seen them bent onto a pretzel shape without kinking. I picked up a few pieces of it to redo some fuel lines, great stuff. If I ever redo the brake lines in mine, that's what it is going to be done with. As far as the pvc coated lines, they should have a greenish color to them, they can be bent without worrying about the coating. They can also be bent in a much tighter radius than standard brake line. Not as tight as the copper-nickel, though. Only time I ever had issues with the coating was if I had to cut and reflare the line. The serration on the die stock for the flaring tool would dig in and mar the coating.

Just to set the record straight, the FLAPS was O'Reillys selling Edelmann RhinoHide lines. The counter jocky called them PVC, but according to the web, they are PVF coated. | | | | Joined: May 2006 Posts: 8,351 'Bolter | 'Bolter Joined: May 2006 Posts: 8,351 | I know which lines you're talking about now. I redid the fuel lines on my S10 with those a while back. Good stuff, easy to work with, other than the aforementioned issue with the coating getting marred during flaring.
