I am replacing the slave cylinder line with a new braided line. It is leaking near the slave cylinder.

The nut at the other side is seized. I have the right tools but cannot for the life of me undo the nut.

Any ideas on how to loosen it? I already put some WD-40 on it.

since you have a new line, you could heat it up smokin' hot with a MAP gas torch and it should come apart. it will ruin the plastic line, the line will start on fire and drip flaming/smoking brake fluid all over.

i couldn't get mine apart, the line was rusty enough where it broke so i spliced in 1/4" NiCu line a ways back under the line and ran that to the slave, making a compliance loop to absorb engine rocking.

Do you have a 3/8 impact gun? If so, Iíd cut the hose, heat the fitting with a torch, and buzz it off with a 6 point socket holding the line nut super tight with flat jaw vice grips. That should do it.

Or, carefully cut the nut end off with the tool of your choice.

Vice grips can usually get a better hold on either of the nuts, especially if they are rounded.

I have a specialty vise grip for exactly this purpose. It has saved me a lot of headaches.

Best case it comes loose and you are good to go. Worst case, the nut may be seized to the hard line, and will twist the hard line with it. In that case, you may also need to replace the hard line.

Wyze grips slips as well. Got it as tight as I could. It will not open.

Is there a way to cut the mental line and put a new fitting at the end?

Iíd do everything thing to avoid cutting the hardline. Use the grips on the hardline hex to hold it secure. The part to sacrifice is the hose end. Once the hose is gone, you can get a socket on the fitting.

Nothing worked. Even wise grips as tight as I could get them on the nut.

Iím thinking of cutting the hard line right in front of the nut and then putting a new nut on and flaring it again.

Any idea what kind of flare it is? The thread is 12x 1.5 I believe.

I think you are misunderstanding me. The hardline fitting needs to be held stationary in this case. You need to unscrew the plastic hose fitting off the hardline fitting. Cutting the plastic hose at the fitting letís you get a 6 point socket on the hose end. It sounds like you donít have torches or a small impact gun. A long ratchet with the 6 point socket will likely break the hose end loose.

If you cut the hardline, there wonít be the room to get a nut on there and flare it with a bubble flaring tool that you likely donít own if you donít have an impact gun or torches for heat.

But by all means let us know how it goes if you cut the hardline.

I understand how it all works. My issue is the 12mm nut on the hard metal line got rounded. I can get a grip on the 14mm nut which is on the plastic line.

so the metal line is spinning no matter what tool I used. Brake line wrench, wise grips etc.

In the picture below, the tool farther away from us is spinning on the nut. The closer tool got a perfect grip.

Here's what I want to do.I just need to know what kind of fitting is at the end and what kind of flare. Maybe someone here knows.

VW uses the DIN/ISO flare. take your new hose to NAPA and find which size, like M12, fits the end of the hose.

the line you've drawn isn't enough room to install a fitting and flare the tube. you'll have to go further in the middle of the van, cut the line, put in a coupler, and extend the new line back thru the frame with the new end already on it to mate to the hose. the advantage of doing this is that you'll replace the section of line that has gone thru the frame grommet, which rubs off the protective coating and the steel line then rusts. use a NiCu line and rust is not an issue.

good info on flares:

I can pull extra line through. It has some bends and I can get more out of the hole so I can flare it properly. I ordered a tool from Amazon and some fittings.

Napa also sells various lengths of brake line with the proper metric ends. You might be able to replace that entire hard line leading to the next fitting up front.

Take a dremmel tool and cut the hose end end to end a few times. You can then likely get it off. Use vice grips to hold the rounded tube nut while you thread your braided hose on.

Right now I put a fuel hose clamp on the end near the slave that was leaking. We'll see if that stops the leak.

The next step will be to cut the end of the metal line and put a new fitting there. Hopefully I got the right fitting.

That's the fitting I ordered.

This is the tool.

One of these is handy for getting a straight cut needed for proper flare. [url] https://www.amazon.com/RIDGID-32975-Quarters-Tubin...sc=1[/url]

If it's not too late...............WD40 is not good for breaking things loose. Try a 50/50 mix of acetone and cheap ATF. Let it sit overnight then put a bit more on. You might get it loose then.
