Still having problems changing brake line
I am trying to change out the rubber portion of the front passenger brake line on my 1996 F250 4x4. I got the fitting at the caliper off with no diffuculty at all, but the fitting holding the rubber portion to the steel line at the frame is giving me problems. I have been PB Blastin' the thing for days and got my torch on it tonight but still haven't gotten it apart. Someone told me that it is probably just corrosion holding tight, but I just want to make sure that I am doing things correctly (I am a rather inexperienced mechanic, learning as I go). I don't want to strip anything. Should I be able to just wrench on the rubber section while holding the steel section? Does the threaded piece on the steel line spin independently (around) the steel line itself? There is a flattened section on my replacement part where it goes through the bracket on the frame. Is the bracket keeping the existing piece from spinning? If so, how do I get it loose? I know this shouldn't be that hard! I really appreciate you guys' help.

The top metal fitting threads into the metal fitting on the end of the rubber hose. The metal bracket just holds the hose in place using a slide-on clip and does not prevent the hose from spinning. You should be using Flare-Nut wrenches to remove these type of fittings. I would place one wrench on the bottom rubber hose fitting such that the wrench is pointing to the right and up against the frame to prevent it from moving while you are turning the top fitting. It is much easier to loosen stuck fasteners by hitting the wrench in the proper direction with a hammer rather than just pushing or pulling the wrench. If you booger up the fitting you may need to use visegrips to remove the fitting. Good luck.

do yourself a huge favor and replace the metal brake line as well. you can get the straight stock most anywhere and it is very cheap too. You can bend it by hand and you won't have to worry about blowing that line out. Given your year, and if you truck sees any salt, I would replace all the metal lines. I did that on mine and you wouldn't believe how many broke when I moved them slightly.

Looking at the marks on the line, it would appear that you are trying to spin the wrong part. The big hex will not spin. You need to remove the hard line from the back side.
This would be the smaller hex. The big line is held in with a flat, so you will not need two wrenches. Simply remove the small hex from the rubber line, then remove the clip from the bracket and the line will come right out. Install the replacement and you can bleed the system. You will find it much easier to start the fitting before you install the retaining clip.
Good luck, brake lines can be a little bit tricky.
