Ugh, it is. They clearly never meant for these brake lines to replaced without first draining and removing the refrigerant lines for the A/C that run above them behind the engine. Keep in mind this is like 6 feet of hard brake line in a very weird twisted shape. I managed to get it in there anyways, but it took a lot of very careful finagling and very slight bending of the tube to get it into place. The other easier stuff that I did take off to get access was the windshield wipers, the strut tower brace,
all of the upper plastic crap (battery/brake/lower windshield area), and the right upper intake tube.
Anyways, it appears I've fixed my leak, and so therefore the cause most likely was that I over-torqued that one flare connection. At the very least, I can't induce the new connections to leak cramming my foot down on the pedal as hard as I can repeatedly with the car off. Obviously I need to recheck w/ the ABS and power assist up and running later. I bled this one wheel a bunch to try to remove the bulk of the added air from replacing the hard line. Tomorrow I'll reassemble all the little stuff I had to remove today to put the line in, and do a proper 4-wheel bleed in the right order (I have enough speed bleeders for the whole car now), and then hopefully all this brake stuff will be behind me
