Technical Copper-nickel brake lines

That’s the way to go. Used it on my ‘41 Plymouth. Easy to bend. Look into line straightening tools to get a good straight line for the frame rails. Simple trick is to just drill a hole in a piece of wood and slide the line through it. Use a bending tool! Tweak bends with your hands. Make sure you put fittings on before flaring and in the correct direction! Haha!

 

I used Nicop on my 40. I also used it on the fuel line. However, for the fuel line it had a black flaky stuff that clogged my fuel bowl within minutes. So I went back to rubber for the fuel line. I’m about to switch it out for braided rubber.

 

Something strange here... obviously black flaky stuff would be really bad for brake systems too.
Actually worse than for the fuel system.

Yeah, that's not normal. The particular piece of line you were supplied with must have been contaminated. All the stuff I've used was bright shiny clean and remains that way in use.

 

Well I don’t know how I feel about you cheating and giving the answer to the whole cl***?! I wanted the cl*** to review the periodic table...

 

You're thinking of straight copper. Nicop is much more forgiving. The average flat rate tech is a complete dumb*** and even they manage to work with it.

 

Oops.....

 

Now it'll be on the final! Good going...‍

 

Is the Speedway line from china? Doesn't say... https://www.speedwaymotors.com/Spee...-Line-Tubing-Roll,575584.html?sku=40700022-25

 

I would ***ume so everything else they sell is.

 

Are the fittings different than standard steel line fittings?

I use standard fitting for steel lines

3/16 or what ever size tube you choose is measured in OD , so fittings are made to a standard ID size . The fitting will be correct for the tube no matter where it’s from .

 

I'm getting ready to do the brakes on my new to me '32 Chevy. Have been wondering about this material for some time. Sounds like amazing stuff. I'm convinced! Thanks to all contributors here.

 

It's all I use.
However I am using 3an fittings for brakes

 

Copper-nickel (NiCopp) is actually widely used for brake lines now and is DOT-approved, so it’s perfectly safe when installed correctly. A lot of newer vehicles even use it from the factory because it resists corrosion way better than traditional steel.

The big advantages are exactly what you noticed—easy to bend, doesn’t kink as easily, and won’t rust out like steel lines do. As long as you’re using proper fittings and making good flares, you’re good to go.

The old steel lines are still fine, but honestly, most people prefer the copper-nickel now for ease of use and longevity.

 

Just to add, don't use pure copper tubing. That is not the same stuff. Pure copper is susceptible to fatigue cracking from vibration, that is why you should not use it for fuel or brakes. It is also not as strong and theoretically may cause a problem under high brake pressure.

 

No

 

1. Beware…some of the advertised CHINESE “Ni-cop” brake lines are actually copper plated steel! They are cheap, but not anywhere near as pliable!

 

I got some of that the first time, really stiff. Second try I went to some vendor I'd heard of, got the good stuff.

 

Customer came by with his Amazon bargain Co/Nic. brake for project we are doing for him. Even though I told him earlier, get it locally at parts store. Yup, copper plated steel. Some people never learn.
