Actually, as I lay in bed last night obviously not sleeping, I had one of those bolt upright, aha moments.
The TL;DR is that I think :TB: had a damaged line. I think SS are as good/better than rubber lines. Basic construction is similar, just the outer jacket material is different. But I'm limited in my data set and am open to anyones alternate opinion except RCB because he rubs me the wrong way.
...TFL;NGR below...
Either like :pb: said, they were really MIC junk lines (but :TB: said they were big name, so???) and that's why they failed. Or I'd actually lay it out there and say there was a problem with his lines that was bigger than them being SS overbraid and here's why (gods, I hope that RCB knucklehead doesn't read this. Or maybe I do. IDGAF):
Both the OEM style rubber hoses and the aftermarket SS braid overwrapped lines have the same teflon (or similar non-reactive, flexible, non-metal) inner liner that actually contains the brake fluid. The SS ones add a braided overwrap to reinforce the inner tubing and prevent it from failing under pressure. The rubber hoses are actually a rubber and fiber thread reinforced composite overwrap that does the same function.
However, the difference between the two is that the SS is less compliant so it's not going to expand (very much; atomically it is moving, yes) where as the rubber overwrap will give a bit more. Both attach the end fittings in a similar manner so all things being equal, they should work just the same.
In the end, the way they fail is the fitting separating from the hose because of a poor initial fitup, or they split because of damage. Now this is where SS is a little bit less tolerant than the rubber. If you kink the SS threads, they'll break and without that reinforcement the inner liner will blow out under pressure. Rubber overwrap is a little more forgiving, but it is susceptible to dry rot over a really long time.
Again, anecdotaly, I can say that I've seen bulged rubber hoses that were needing to be replaced and I've never seen a SS line fail that was assembled and installed correctly (seen plenty fail that were built by a moran).
guys, do as you please. I'm not telling you what to put on/off your cars. What I do know is that the SS lines I had were of a reputable brand- I still had the rear ones (the original owner never installed them), but I just tossed them when I bought the car as I had no intentions of using them, so I don't remember the brand.
Take it for what it's worth. I've heard/read plenty of times, in car magazines, forums, etc, etc, etc, where it is advised to not use SS lines for DD purposes. I'm sure climate plays a role in all of it too, so living in texas might not be as bad as living here.
Again, those lines were on my car for about +/-6 years. I know that for sure. If they lasted that long, I highly doubt they were compromised to begin with. I'm pretty sure I didn't damage them either, as I try to be as careful as possible whenever removing the caliper. I always use a bit of rebar wire to hang the caliper out of the way and make sure the hose isn't being kinked or stretched or whatever.

Not unlike the guy who I was ordering the 07-08 base display from. He says he can get the harness, turns out he gets the wrong one. Gets another one finally, then ships the thing to me. I wait and wait and message him he tells me it can take up to 3 weeks.
Yesterday he checks at his local post office, the lady made a mistake and wrote 2 lbs ont he package and it weights 4 lbs... so they couldn't send it and she didn't have his contact info.
I bought that shit JUNE 27TH!
wtff.. TB, bruh.. don't pump your brake if you lose pressure when you're stopped. It could be your brake booster, but more than likely it's either low-fluid, leaking fluid, or shit MC. Either way.. pumping could be dumping. As long as one of the valves has fluid, you have stopping power. That's one of the reasons the rears and fronts are split.
I've never heard a line popping like that out of the blue. Was it the banjo fitting? Regardless.. SS lines are bullshit. If you can feel the difference in the brake pedal, it means the previous brake hoses were probably old and needing replacement. They're just another bullshit mod.
Fade.. are you fucking kidding me. Brake fade has nothing to do with lines/hoses/fluid and everything to do with pad on rotor. Shit fluid with moisture, algae, air and bullshit compresses and reduces the fluids efficiency to properly apply pressure. This is exacerbated by heat (P is proportional to T motherfuckers).

If anyone has brake fade on a DD (linked to their fluid), either you're driving like a maniac or your fluid needs to be replaced real bad.
Disagree about SS lines. They improve pedal feel, not squishy at all. No matter the age of the OEM brake lines they'll always feel more spongy than braided SS lines.
I missed your post in 105k.. LMK if you need any help brah! Don't forget the Tstat.
Don't listen to the banter in here.. spark plugs seem easy, but the coil is sensitive and you really need to feel it out when putting them back. Don't overtorque the plugs too.. on the flip.. definitely don't forget to torque them.. or you might be rethreading or rebuilding.

No need to use torque wrench though, rcb told me just do it by feel.. Imma trust him, he's been building front ends for 100 years.

It's all fucked now. I was pumping it because I didn't know what the fuck was going on. Like I said, I checked the reservoir and it was still pretty full as soon as it started happening, so I was confused as to what the issue was. Everything is likely empty now. I won't have time this weekend to tackle it, but I'm gonna buy new OEM lines for the front and bleed the brakes. Should be okay afterwards. Or so I hope.
If not, I'll start replacing whatever is fucked now. I'm just glad the failure happened when I was stopped, as opposed to driving at 100km/h. I could have ended up

Just tighten it to 13 with your hand you incompetent idiot whos never turned a wrench for a living once you do it enough you know the difference not like a stupid head like you 8 and 13 are different and you know because of your muscle memory and being ASE certified best of class in 93 on my mother side

Tests have shown that while SS brake lines (depending on the mfg), might resist hose expansion somewhat more than OE rubber hoses, it would result in a mm difference in pedal feel.
The fuck is wrong with y'all. Who the hell does maintenance on their cars. Just drive the shit, put gas and an oil change every year. You will be fine.

Chewed through a caliper (looool) exiting the highway when going to the gym. Press the brake slightly and it sinks, oh shit... Rolling down to the red light where people I stopped. I let the people go back up and fucking hammer it enough to nearly break my neck. Stopped good enough but then I knew I had very little braking power from now on, but I was like 3 turns from the gym.

We had a well known and respected member here go through this. He did a BBK.. I think new lines and calipers. Can't remember member.. maybe MMADE22.. he's long gone now.
He was on the freeway going at a decent click when he saw some traffic up ahead. He hit his brakes and heard clunking, then lost pressure. Long story short, his caliper got loose (possibly stripped bolts) and cut free snapping the brake hose. He lost braking power but was able to still get the car to slow down by staying on the brake (still had rear braking bias) and getting off the road. He got lucky. I think he had some body / wheel damage.. but for the most part came out of it unscathed. I've been through a similar situation with a failing MC and brake booster.. fun.
^Of course I'll never know. Unless one of you plebs quote him. LOL
I can see it now "Blah blah blah only pad fade matters blah blah blah nudes of your wife blah blah blah"
blah blah blah
I'm sincerely confused as to why you're being an asshole? Because he disagreed with your opinion? If that's the worst thing that happens to you today, man, you're a lucky guy.
