Hello all,

The M37 had "armored" brake lines which were basically the steel line with a a steel wire wrapped around the tubing. I know that some of the vendors are reproducing these lines for those who are doing restorations which is great. My question is this....is there a modern brake line tubing that updates the original lines? I'm thinking like a braded steel cover or something like that. I'm looking for something commercial off the shelf that can be used for the brake line and give it "armored", off road, protection?

Any thoughts you all might have would be helpful.

Thanks

You can buy stainless steel spring tubing armour. It’s exactly like the original, except in stainless.
I figure that plus one of the the modern brake line alloys like cunifer would appropriately modernize things.

The problem I'm having with the spring armor on the brake lines is when I pulled my truck apart the coils around the tube were packed with mud and dirt and the lines were rotted out under all that muck. That's why I'm thinking there has to be something better for "off road" use that won't get packed full of mud and dirt. Or maybe I'm just over thinking this.

I did my lines with the Copper nickel ones, and was able to reuse some of my armor and bought more. I think the likelihood your lines will rot in some reasonable future is unlikely. Your perhaps original lines may be over a half century old. I wouldn't worry about it. NV

This is the solution I went with.

When I replaced the brake lines on my Ram charger I was able to buy the Armor Springs from Amazon and make up my own lines. https://www.amazon.com/dp/B01IRQXDZC/re ... s9dHJ1ZQ==. I guess most auto parts store should have them also.

Brake lines on my M37 look in decent shape, but the coil surrounding it (the armor) is corroding. Its 15ish years old at youngest, so its not shocking.

Would coating these brake lines in grease, then putting the entire line in a hose, I’m imagining a tough garden hose but smaller diameter, be useful to preserve this metal and protect it? The ends do not appear to be so large as to make this impractical.

I see Midwest sells a line replacement kit, which I will likely do at some point, but I sure would like these replacement lines to last a lifetime.

Redleg, I think I'd replace the armored lines then coat the new armor and lines in "Lizard Skin"-supposed to last a long long time.
Just my 2 cents,
Gary

Here's where I shopped for the brake components.
Good experience with product and shipping.
