I'm reporting back to cry and offer advice.
I just spent 5 hours removing the rear brake lines from the ABS pump back to the caliper flex lines. Boy, what an obnoxious job. I've done some horrible jobs before, and this is right up there. At least I realized quickly I was going to have to remove wheel well liners and such. I'm quite sick and skipped lunch so I'm sure that didn't help. =P
So everything is pretty straightforward except that joint for the rear-right wheel where it takes a 90-degree turn to go across the width of the car above the rear sub-frame. That one as has been mentioned is a total bitch, but if you're like me and removing absolutely every piece of hardline for the rears, you can remove it from the caliper flex line at the rear-right wheel and fish it across the car* enough to bring that junction within easy reach of normal flare wrench tools. So no crows foot necessary for removal. Installation might be another story. We'll see.
Cheap, foam ear plugs are nearly perfect to block up the exposed ports while you wait for parts to arrive.
One other piece of info. Again, if you're like me and removing everything from the ABS pump back, you'll find the rear-left line has a M12x1.0 thread into the ABS pump, as well as one more down by the front-driver's rocker panel. So not just one junction with M12, but two for a total of three M12 male hardware and one double-female M12 joiner.
At least I know what hardware I'd like to purchase now, and that 25' of tubing won't be nearly enough (I need about 34 feet if I make no mistakes). And now I know all about those one-time use plastic pop rivets for the fender liners (another tool to buy!). Wish me luck on the install. These lines that go over the wheel arches look insane to reproduce. We'll see.
*You might have to half-remove the right-rear damper (just the bottom bolt) to allow for the hardline to get into position. I had to. And that's an obnoxious job as well if you don't realize there's a non-captured nut on the other end. That's not how my E36/8 nor E91 are. Live and learn. At least I didn't totally ruin things like I thought I had when the bolt just never backed out and kept spinning with aluminum chips falling out.
