So I ended up pulling up the seat after all. You guys were right, there is definitely not enough room to work with before the coupling, and pulling up the seat was super easy. I will still try to flare the brake line after the coupling a bit further back from the spot marked by the red line. I really don't want to mess with the other parts because they don't look bad enough that they'll break, but I am afraid of stripping or tearing the brake lines or having to replace the rubber brake hoses if I screw something up. I can deal with that in the summer when I have more time. I ended up buying the ni-copp line (yes, I had a bit of sticker shock when they rung up the 25ft spool) and fittings at an auto parts store. Scratch that. 3 auto parts stores. I'm starting to remember why I hate going to auto parts stores versus just buying stuff online. Constantly over priced, constantly out of stock, and constantly wrong parts sold. I wish I planned this out better, but I digress. It's amazing how much easier ni-copp is to work with. And now I have the fittings, brass couplings and the brake line. Hopefully I can finish all of this tomorrow. I am worried that I'll end up stripping or breaking the bleeder valves on the calipers though. Planning to blast them with WD-40 and hopefully that will be enough. As for covering the brake lines with a protective shielding, would I just be able to spray them with rubberized undercoating to form that layer of protection? Or is that not a good idea. P.S.: Numbchux, thank you very much for the detailed write up. I will definitely follow all of those steps when I get around to redoing this the proper way.

Hey guys! New to the forum, new to being a subi owner, and new to doing brake lines. The brake lines around the coupling in front of the right rear wheel well are rusted and I'm leaking fluid. I've read a few posts on this forum that talk about this issue and people tend to run new brake lines from underneath the rear seat to the calipers, or so I gather. What I am wondering is if it is safe, and legal to simply cut out the 6 inches or so of rusted brake line and splice in a new brake line section using 4 fittings and 2 unions on each line. In the picture, the red section is what I want to replace. I'm not talking compression fittings, I'm talking proper double flared unions and fittings. I just need a temp solution for a couple of months until I can get it on a lift and fix everything that needs fixing in the rear end. So I am wondering if this is doable. I definitely do not plan on dropping the tank to get to the brake lines. If what I want to do isn't a viable option then I am wondering if anyone has a recommendation for a new, easier path back to the calipers. Thanks for any help!
