Brake line in frame
I want to replace the rear brake line on my 69. It is connected inside the frame. I have been trying to soak it with penetrating fluid. If I can't get it loose I will have to replace the brake line from front to rear. My brakes work very well. I just need to replace the hose. Any ideas on how to get it freed up?

Re: Brake line in frame
Use a tubing wrench after soaking it again and again for several days with a quality penetrating oil like "Deep Creep". Then carefully try it attempting to both loosen and tighten. If it doesn't go, more penetrating oil applications and time.The longer you are patient the better chance you will have of breaking it loose without twisting and ruining the line. When I've been patient, I've been successful. When I was not, I replaced more than I had hoped.

Re: Brake line in frame
Thanks. I have a little rag wrapped around it now. It is soaked with penetrating fluid.

Re: Brake line in frame
You might try a little heat also.
Sometime a small propane torch is enough to break loose the rust. When you reassemble the new hose,... use a little anti-seize on the threads,... and it will never happen again. |

X2.
I've done that many, many times-- turn the nut yellow, then they come right loose with no fuss.

Re: Brake line in frame
I suppose this line connects to the flex hose coming from the front of the truck? If I am correct, I would have a new flex line, and new metal lines to both rear wheels available. What I have experienced is that the metal line seizes to the metal nut. This keeps you from turning the nut on the line. SO, if you cut the line, remove the clip holding the line to the frame mounted clip. and unscrew the flex line from the metal line, you should be able to unscrew them from one another. Then you will need to replace both with new lines. HTH

Re: Brake line in frame
You can get that anti-seize in a roll on stick, beats using the brush in a can, and alot neater.
