Brake Line Material

Stainless looks pretty but thats it.
Very hard material and leak at the fittings.
You can round off the flare nuts tightening them and still leak.
Stainless does not have the crush value which helps seal the flare against the fitting.

I recommend fabricating your own lines using standard steel line and a good flare tool kit. Done right, last for years.
For ease of installation at my work for example nickle plated copper lines are easy to work with.
Hope this helps

Yeah I've heard you can manipulate that stuff like butter, but it sounds like steel will be the better bet for longevity. Thx
 
IIRC, nobody repops C body lines.
The rear axles lines for B/E cars are the same as C's.
I removed my lines carefully from the car, laid them out on the floor and duplicated the bends using a tube bender.
It is not hard to do just pay attention and take your time. Think of the money you save, lol!
My vote is for plain steel line.

I'll expand Lea's thought here. NiCopp is the way to go.
 
Well uh, I've already got the tools and line on order and they've shipped by now. Maybe if I manage to screw up colossally then I'll go for that inline tube pre-made line. Wasnt aware it was available in that catalog, just looked on the site.

Zinc coated steel is OEM. NEVER use copper for a brake line. It will crack under stress. There are copper coated steel lines available.
I prefer stainless steel. It can be difficult to work with as stated but with proper tools and patience it will be there forever. One less thing to worry about.

Their site is a pain.
Look for their Mopar catalog and scroll through.
They offer a lot for our cars that don’t seem to show up if I just search the site filling model year etc.
They are about 8 miles from me. They put on a spring car show at their shop where I bought my parts just by asking a guy at the counter. I should have grabbed the catalog!

Oh I don't know NiCopp has been used in Europe for decades now and no issues. If it's good enough for their anal-retentive rediculousness it's good enough for me.
 
I hope nobody is talking copper tubing, such as a roll of tubing from Home Depot for air conditioning or water systems. Using that for an automotive brake system will result in someone getting killed. Sooner than later.

Nickel/Copper tubing, designed for use in brake and hydraulic systems is a whole 'nother thing.

And yes, the Inline website is awful, and their "catalog" isn't much better....very hard to use. Plus, you have to think about what other Mopar might use your needed item because they don't list everything. For instance, the two-piece fuel line from pump to carb isn't shown for a Cbod. But of course it's the very same item for a big block Road Runner, etc.

I think I had to do that when I bought my tank to pump fuel line kit. I don't recall it being listed for a 1970 300, but was listed for some other car with the same wheelbase. Worked perfectly.
 
Copper Nickel brake line is not copper...... It out lasts steel lines and is easier to work with...

It won't rot from the inside or at fittings.....

I use it for. Everything, fuel lines, brake lines, trans lines, etc...

I'm going to use Nickle-copper line in my F100 when I switch over to a dual master cylinder and replace all my lines since I need to now add a distribution block. Already have the material.

Copper Nickel brake line is not copper......
Yep, far from it. Our US Navy uses copper/nickel piping in the high pressure seawater systems on board our warships (there are several systems that use seawater, I won't elaborate here). The piping is impervious to EVERYTHING, massively strong, and the pipe and its fittings are massively expensive....rightly so.

Most of those USN systems also incorporate iron, yielding inconel, the mix I remember most is Inconel 600.

Typically used for gas turbine uptakes (the exhaust system) and hull valves, plus weapons systems applications. Very serious stuff, that Inconel. Corrosion resistant? If you had Inconel pipes and mufflers under your Cbod, they would last about 1900 years. Or 2900 years. Too bad Chrysler didn't make trunk floors and quarter panels out of the stuff!
