Brake line damage, help

hey guys i bought some stainless steel brake lines, i was trying to loosen the oem fitting with a 10mm wrench and it kept sliding causing damage to the nut, i wasnt able to remove them after causing damage to the nut so didnt attempt it anymore. i sprayed them with wd40, put the 10mm wrench on and tapped with a hammer but no luck loosening them. now i dont know what to do since the nut is damaged? should i just take to pro to do the swap???

 

Try a line wrench or if you absolutely have to, a small pipe wrench.

 

pipe wrench, monkey wrench wont that make it worse? they're easy to change just hard as hell to loosen.

 

Try the line wrench first if you still have some points to grab on to, that's what they were designed for is to remove line fittings so you don't round them off. If you've rounded off the fitting then you're pretty much past the point of no return already so the pipe wrench isn't going to do much more damage.

 

going to go get a good set of line wrenches and try it out. thanks for help guys, so line wrenches have more grip?

 

Yes, they wrap around more than just the two arms of a normal wrench. You might find them as "flare end wrench" or something similar. I bought a set at Harbor Freight for $10 after doing the same thing as you.

 

The cheap metal in the fittings will round off, even with the line wrenches. Get a double flare kit and make a repair piece. Do a few practice ones first.

 

Are you referring to the nut that is attached to the original rubber lines?

If yes....
PB blaster (penetrating lubricant) and let it sit 15 minutes. Spray again, let it sit. Try a flare wrench of the proper size. Use vice grips if you have to and get a really tight lock on it. Since you are replacing these things, it doesn't matter if you destroy it. If you have to...... use a torch and lightly heat the nut. Have fire extinguisher ready. Metal expands and the whole idea is to heat the nut so it'll expand.

And ...if that doesn't work... get a dremel tool out and cut a slit down the side of the nut CAREFULLY. Spread the slit and pop it off.

 

so if i cut them how do i replace the nut that goes into new stainless steel brake lines?

 

Did the new ones not come with their own nuts? Mine did.

 

Do you have any pictures? Don't start cutting unless we're totally sure we know what you're referring to.

But yes...the new lines should have new compression nuts on them.
