Brake line hose removal?

[Matt J.]

What is the best way to remove old brake hoses without damaging the hard lines? Heat? I'm working on the front brakes at the moment. Banjo bolts at the caliper were easy but I'm having trouble at the fender well connection. I don't want to destroy these soft metal fittings. I just did a 4" lift so I need to install my longer hoses. Thanks in advance.

Oh BTW, I have the correct flare nut wrenches but the fittings seems like they want to round off if I crank on it too hard.

I usually drench mine in Mopar Rust Penetrant, and if need be cut the old hose to get a box end or socket on it. If Mopar knows anything, they know rust.

Yea i broke one of mine had to run a new line. I just spray them with pb blaster if that dont work will probly have to replace the line.

That's a good idea. You're right, if I cut it I would be able to get a 12 point socket on it. Thanks.

You are not the first person to mention that Mopar Penetrating oil. Sounds like good stuff. Now I have to have some. I wonder if that stuff is available at Kragen, Autozone etc... I soaked it with PB Blaster yesterday but, it obviusly did no good.

Thanks again.

If the proper flare nut wrench wants to round the fitting then use a pair of vise grips on the hard line fitting until you break the line loose from the rubber line. I haven't had any troubles doing it this way and haven't ruined any fittings "yet".

Sweet... I just removed them. They didn't want to come off with just wrenches(open end, flare nut wrenches) but with a combination of vice grips on the hard line nut and cutting off the rubber hose to accomodate a socket for the hose nut in the front, they broke loose quite easily. The threads don't look all mangled up either.Totaly reusable hard lines. I'm glad I didn't have to replace any hard lines because I don't have access to a tube bender or flaring tool at the moment. Thanks again everyone. New lines are going on tomorrow. I'm picking them up from 4wheelparts after work.

If and when you DO need to change hard lines, most auto parts stores have them already flared with the nuts on them. You just have to measure for the right length and bend them by hand. I've had flares crack before, so I've had to change a couple lines in the past.

Thanks again everyone. It's coming together nice. Installed new S/S lines today.
