Help with 14bff swap

[la_blazer82]

I am trying to swap out the rear 10b for a 14bff, and am stuck trying to unloosen the brake lines from the fitting just above the housing (where both brakelines from each rear wheel meet). I used a 3/8 wrench for fittings, but the fittings won't loosen. Without this, I can't get txle off. Already have everything else unbolted. Any suggests??

If I can't get this done, looks like the axle swap isn't happening this weekend, and no 35s /forums/images/graemlins/frown.gif

You'll probably wind up having to replace the brake hose after doing this, but it will get the lines loose...use heat... /forums/images/graemlins/weld.gif

Good luck!

You shouldn't be using a standard 3/8" wrench. A special 3/8" wrench should be used that wraps almost all the way around the brake fitting. I forgot the name of them though. /forums/images/graemlins/doah.gif I stripped a brake fitting once myself and used a pair of vice grips to grab on to it tight and it came loose. Also if you have one of those little propane torches, heat the fitting up just a LITTLE, remember that you have fluid inside the line. I wouldn't use a oxy/acc torch.

Use a line wrench. You can also Ice or dry ice the line above and below the fitting and a little heat on the nut. Good luck I am about to do this myself. Ya think if lines have been on a truck for 34 years they might be a little tough to remove???? /forums/images/graemlins/thinking.gif Good thing I have everything new. /forums/images/graemlins/thumb.gif

Like the others suggested, use a flare nut wrench and a little heat if needed.

Exactly what I was using. Thanks for the replies. I ended up using a little heat and a smaller Vise. Ended up changing out the line with a ProComp 4" extended brake line.
