Front brake hose replacement 41 Ford truck

The rubber hose has disintegrated and fluid is leaking out. With application of PB Blaster soaking over a week, what do you think my chances are of the hose fittings actually breaking loose at the wheel cylinder and brake line fitting?

I don’t have the means to pull the wheel where the truck is if something goes awry. It would have to be towed to the shop. Figure it’s worth a shot, right?

Wheel cylinder end has a good chance of coming apart. If it's the drivers side, it has a good chance of coming apart as it has the banjo bolt. The pass side depends on if the fitting is rounded or rusted to the tube.

If the hose is being replaced you can cut it and use a ring spanner on it. That will get a better grip than an open ender.

My experience is with cars I don't know if the truck is different but you can't do anything but try.
 
Agree with both posts, thank you!

I figure the steel line will probably come apart, so I’m anticipating replacing that to the master cylinder as well. I despise bending brake lines lol.

I suppose the next logical question is cracking the bleeder screw loose... are they notoriously weak or anything?

Get the cupronickel brake pipe, it is easy to bend, and easy to flair and looks like original copper plated steel pipe
 
As a safety note, don't heat the hose fitting with a torch. I had a hose that I couldn't break free, so I decided to heat the crimped section of the fitting with an oxy/acet torch, then cool it with a wet rag in hopes of loosening the fitting. What happened was, the heat caused the hose to explode out of the fitting, missing my head but spraying hot brake fluid on my face. No serious burns, but thankful that I had safety glasses on. Won't do that again!

Thanks for the heads up! I would not have used heat but I’m glad you made it out without any lasting injuries.

I've heated just the nut a dull red and let it cool on its own and they always break loose. I use a real small tip a 00 or 000 tip so you can concentrate the heat just on the nut. We had F600 4x4s up in the deep snow on the mountain. The nuts rusted to steel line tubing. You have to use your judgement as to how rusty that tubing is. It might be safer to just make new steel lines. Put a "little" never-seize where the inside of the nut touches the tubing, making sure its will not get into the brake fluid. Next time it will break loose easily.
