Need help on dealing with brake line nuts

[wilfredwong]

I striped one of my brake line nuts when I was trying to change my brake lines.
Also, when I try to loosen the nut for another brake line, the whole brake line (both hard and soft line) is twisting together, making it impossible to be loosen.
Does anyone know how to fix it...or should I just ask for someone's help?
I want to try to learn and fix it, but on the other hand I don't want to make it become even worse.
So far there isn't any leak and should be safe to drive.
DIY+Lack of skill and exp=KIY
PS:The nut is the one on the hard line...

Update 04/05:
Today when I inspected my car again I realized I can actually see the thing without take off the wheel, so I decided to take a photo of it.

If the nut itself is stripped you can just get a new nut. If the thread hole is stripped you will have to get a tap to retap the new thread (use tapping oil). Best to always lubricate nuts and bolts if they feel tight and never force any thread. If nothing is available at the moment and you gotta go.... zipties are your best friend!

hopefully you read through the DIY before you started. http://www.ft86club.com/forums/showthread.php?t=20311

I found the suggestion to have a flare wrench to be invaluable. basically if needed to loosen the line where the soft attaches to the hard line, you may need to hold the line with one wrench and use the flare wrench to loosen the nut. The flare wrench allows better engagement on the nut. Also may need to use vise grips or pliers if the outside of the nut got stripped.

stripping the nuts (that attach the line to hard line) is a common issue it seems, but pre spraying the area with PB Blaster or WD40 to help lubricate the nuts/threads first typically helps.

Ya, I read that. I did sprayed a lot of PB Blaster and hold the line with either a wrench or a pliers. However those nuts just won't come out. For that one nut thats striped, do you guys have any idea to remove it?

There are several ways to remove a stripped bolt.

1. Screw it back and forth (if the bolt can still be reversed) maybe the bolt will thread itself correctly and unscrew normally (with lots of PB blaster)
2. Power through it and ruin the thread - then make a new thread hole by tapping
3. Drill through the bolt and remove the bolt by pieces - maybe the thread can be preserved
4. Screw it (no pun intended)

I think I forgot to mention something that's really hella important, the nut that's striped is the one on the hard line, not the one on the hanger or the soft line...

I'm not gonna do number 4 no matter what

The general advice in this situation is lots of pb blaster, vise grips and heat. Vise grips may work where pliers do not. And use a blow torch to heat the nut to help it loosen.

If I remember right the nut is on the soft line not the hard line. The hard line is just threaded so when you get it off, the new SS line has its own nut that threads onto the line.

So last resort could be to cut the soft line and using a stripped nut remover tool remove the nut. If you are uncomfortable with this it might be time to get a pro to take a look.

IF you already rounded off the nut, I am going to assume its on the hard line going to the soft line side, the only recourse is to use a vice grip to hold it and turn it. IT will be better, due to a picture can help, if you can post the picture of what you are trying to remove / loosen.

Maybe I'll post a photo to let people see how the situation is, I might actually find a pro to fix it, but I just wanna know if I can fix it myself.

PB Blaster and a long pair of Vice Grips (Work = Force x Distance) will take care of that mess. I had the impression that you cross threaded some nuts and bolts.

lesson learned, get the right tools and use the right methods.

In doing my bbl upgrade with lines, I found that these pressure fit nuts are very soft. I found the exact same thing with the clutch fluid line as well. Wondering if this is true for all of these throughout the car.
