So I hit the brakes yesterday and the travel increased noticeably and suddenly. Stopping power seemed diminished. Parked in mom's driveway, saw nothing wrong at the master cylinder, almost full with fluid. Drove very slowly to the nearest garage. Mechanic put it up on the lift and pointed at a black puddle on the floor under the rear right caliper. "That's your brake fluid," he said. The brake line/pipe ruptured somewhere between the caliper and whatever junction it goes to. Found out later I left brake fluid puddles in my mom's driveway. Not good.
Garage replaced that brake line, said it was about 2 feet of line between the rear right caliper and a brake hose, and also replaced my master cylinder (I knew that was going bad and I had previously planned on getting that replaced today. But new mechanic noticed it had started leaking fluid, so he took care of that too). Mechanic said the same brake line on the left side is rusty looking and should be replaced. Front lines look okay but not great, he said.
I figure I should just take care of the whole brake hydraulic system, lines and hoses. What are my options? Sounds like the labor cost is gonna be high, which makes sense for custom bent and fitted lines. Questions:
1) Are pre-bent lines worth consideration? That could save a ton of money in theory. I see them listed at $155-$190 at USA Parts Supply and InlineTube.com:

I recall I saw a Parts & Illustrations Catalog part list once (can't find it now) that said "cut x-size pipe to fit" so I assume that's how the dealers would have done it. Mechanic who just replaced my line segment said if I ordered the pre-bent, pre-cut lines, he'd try to make them work, but he said in his experience they often are the wrong length and need to be re-bent to fit. Is that true? Anyone have experience with pre-bent, pre-cut brake lines from those two places or other places?
2) What should it cost for custom lines and hose replacement? Mechanic who just did my line segment gave me an estimate of $900 parts and labor for custom lines and new hoses. I wouldn't hire him for the job, his garage is a basic gas-station-plus type shop that mostly does state car inspections. But I was curious what his estimate would be. I also called a high-priced recommended shop and they said it would cost about $1700 for a custom job, and they didn't even want the work because they're so busy. (And in case you're wondering, I don't want to DIY this. I'd have no idea what I'd be doing.)
3) There are two pipes coming out of my master cylinder. What happens between those two and my front and rear calipers? I really don't know. Master cylinder, lines/pipes, a hose, more lines/pipes, then caliper?
I can't find a diagram of the brake lines and hoses in my FSM or Fisher manual, nor in any of the Parts and Illustrations Catalog diagrams on the online GM parts dealer websites, which isn't helpful. InlineTube specifies a "7pc" set. How many pieces should there be?
4) What is stock brake line material?
4.5) Is stainless better? That's offered at both sites above and I see it's advertised as better for resisting rust. I assume stainless is harder to work with and bend. But I do live in sometimes snowy/salty Washington DC, so I'd like to do this once.

5. I asked the new mechanic to get the ACDelco master cylinder if he could. He couldn't and I didn't care greatly at the time. He got a "PRD" brand master cylinder, a brand I have never heard of and cannot find on the internet. Should I keep it and return the ACDelco OEM part I got from RockAuto? Or switch in the ACDelco eventually?
6. New mechanic put DOT 4 fluid in the lines after flushing the old fluid. I believe it should be DOT 3. Should I worry about that?
