81 CJ7 Brake line issues

Hey Everyone,

I'm having some issues with taking off my front right brake line. As well, I'm not entirely sure if I need to take it off.
I've taken some photos, I was hoping that some of you could help me out.




Here is my brake hose, which I am trying to connect to the current brake line. It doesn't seem to fit:



Brake line it's self:



So my question is:
Do I have the right size of hose to fit that line?
Do I need to replace the line?

If so, how do I get that line off?

Thank you for your response!

Which nut would I take off? I'm sorry for my stupidity lol

Demetri,

Hang on a second. That is not the brake line for that fitting at all! That looks like a "through the frame" brake line fitting which many off road people do and street rodders do to keep their flexible brake lines short so they don't get snagged or in the way of tight clearances. Your brake line has a machined slot in it where a "brake line clip" holds it into a bracket... but it doesn't look like the bracket you have there. Do you have the old flexible lines? The bracket with the "through the frame" fitting would have a flexible hose with a hex nut fitting on the end of it to tighten down to that flared fitting.

Take care,

Check out "YJ V6 Conversion" if you want to see a frame up restoration of my 1992 YJ.

Check out "WWII Jeep Photos AND Restoration of..." if you want to see the original JEEP in action...

This line would be the passenger line. I'm not entirely sure on the age, if I were to guess I'd say it's been there since 1981.

Can I take the flare nut off that end of the line and replace it with a smaller one?

Thank you for all of your advice.

Thank you so much for that answer, that was exactly what I needed to hear.

I do not have the old hose as the previous owner shredded the thing.

Here is a website that has hoses that are similar to what I had before, and came up with a simple google search of: "thru the frame cj7 brake hose"
http://inlinetube.com/Brake%20Hoses%...ss/sshoses.htm

Would those be what I am looking for? If so, which one?
