Brake line frozen
« on: October 22, 2017, 01:37:40 PM »
I tried lube spray. Rust bust but I can not turn the rigid line nut to free it from the flex line. I need to replace the flex line due to cracking. Any tips

Cut the hard line and replace both. The tubing nut is already mangled anyway.

Replace the whole line or get a new nut and re flair the tube?

Get the correct size tube assembly and start over... Note usually there is not enough length of the tube to reflair...

Thanks. I guess I have no other options

If you can, take the other end of the brake line off and slip a box end wrench over the brake line. The box end will give you more grip on the frozen fitting
Its better to be a has-been, than a never was.

Another alternative is to use a small pipe wrench.  Just be sure to also use a wrench on the hose side to counteract the torque so the bracket is not bent.  The pipe wrench will probably mess up the nut more and a normal wrench may not be useable on it in the future.

I was in this pickle with my 84 GTI when upgrading to braided stainless hoses. And to make it more frustrating, it was under the floor pan near the beam axle pivot in the rear. My solution was to obtain a inexpensive 12 point box end wrench and with a Dremel cutoff wheel, cut a space in the box end just enough to slide over the hard tubing. Then with some penetrating oil and heat, it snapped loose while saving the flare nut. The wrench was a cheap solution and I keep it for just that metric usage. BTW, I have regular tubing wrenches, but many are too thick to fit in tight places.  :D

 An addendum, If the wrench tries to spread and round off the corners of the tubing nut, Consider installing a Stainless fuel hose screw clamp just to hold the ends snug on the wrench over the tubing nut while breaking it loose. Then remove the clamp and proceed.. ;)
