Sometimes i wonder if the big car makers pay for the salt that is used on our highways up here. Years ago , I'm guessing that at least 75% of the cars that had a rusted out steel line had it replaced with a copper line . Just wondering how many of you ever used copper and what your opinion is of using it . Now if you have never used it , no need to flame the people who did. Just your opinion and why .

no I nwever used it for brake line.
Is this true or false?
"High performance manufacturers such as Aston Martin, Porsche, Volvo and Audi have chosen to install copper-nickel alloy over all other materials including stainless steel brake lines."

I have been told by a few that this stuff is really good.
I was about to try it myself. It's copper/nickel, and supposedly DOT approved for all it's worth.

It's NOT copper, and I have never heard of anyone using copper for brake lines, at least live to tell about it. lol

The 90/10 copper-nickel alloy is far different from the copper tubing you buy in the hardware store.
I specified 90/10 for heat exchangers because it has excellent corrosion resistance in salty water, it's used in heat exchangers on seagoing ships. And it has been tested for use in brake lines. So just as the addition of bit of carbon makes iron into steel, so the addition of 10% nickel turns copper into something much better.
As for the regular copper tubing used for brake lines, sure, it's better than a rust-perforated steel line. But if you're going to trust your brakes to stop you from high speeds or in the mountains (unlikely in Newfoundland) then it had better be more than straight copper.

They don't even make soft copper in the correct size for brake lines.

Yep, huge difference between a DOT approved copper/nickle ALLOY vs. regular copper tubing........which I have never seen used and would never consider using.  Dave

Way back I bought a '66 dart DD & several days later was under it for a more thorough inspection and a PO had used a compression fitting on a line to either fix a leak or join 2 other pieces. Dont remember if the line was copper (iirc it was bronzed color so most likely) so I swapped that out ASAP. I ended up selling it later on & several years later I saw it in a JY (yellow 4 dr), should have asked what caused its' demise

needed to replace a brake line last year,used the copper/nickel as recommended by a friend.That stuff is great,very easy to bend and form into shape as needed,will never go back to steel. Yes,it is D.O.T.
john 
Then I'll order it. The burst pressure ratings they show for various sizes looked fine to me. Plus like mentioned in the Opening Post, corrosion is a big issue with steel. This stuff doesnt corrode.
How long have you had it and how does it look so far?

Ok ,now that you have expressed your opinion on how copper tubing is unsafe. I have some information for you . As I said before copper tubing was used extensively here and sold in all the automotive stores. Not one accident that i know of has been attributed to a copper brake line bursting in the last 50 years here in Newfoundland.We would be one of the first to know as we are automotive inspectors. You cannot physically put enough pressure on the brake pedal to do that . I tried when questioned about it and ended up buckling up my dad's chrysler steering wheel .I then installed a high pressure gauge up by the master cylinder to see what kind of pressure I can get . 3300 psi was all i could push on the pedal . The 70 chrysler had all copper 3/16 line and never swelled , burst , or popped a flair. Do I use it now ? No because they have decent steel line with a galv/aluminum coating on them now . If you don't believe me and if you have an old clunker , install a piece on the old car, get the pressure rating for 3/16 copper and see if you can burst it. I am certainly not advocating the use of copper brakeline , just sayin lots and lots of it was used here in canada.

I seriously doubt they are copper brake lines, copper PLATED steel, yes, copper no.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

Maybe it's in Stores in CANADA , but I have never seen copper line in an autoparts store except for the 1/8" line for oil pressure gauges.
I guess CANADA allows things that would never pass the US DOT so no need to get your undies in a bunch ...

No Not steel, genuine K type copper , soft and pliable.

I have no doubt that it looked like copper, but I have to wonder what it's actual properties were. As said above, the 90/10 stuff is very pliable also. If they still have what you think is 100% copper in your auto parts stores, take a good look at the packaging. If they no longer sell it, there's probably a good reason for that.
