Is copper pipe ok for brake pipes?
ADD - 26/8/06 at 04:28 PM

another question....

Does anyone know if copper pipe is ok for brake lines?. I have done a search on here but get mixed responces, most say maybe some say no. I have just got some from a motor factors which says it is specifically for brake lines, so am reasonably certain that it is ok but need to make 100% sure before I go fitting it.

Again, thanks in advance.

As long as it's specifically brake pipe copper it's fine.

Copper is fine for brake lines and if it has been freshly annealed is easy to form. Make sure it is clipped to the chassis at 300mm centres and placed out of harms way.

Kunifer, a nickel/copper alloy is superior to copper being tougher and more robust and this is ideal for rally cars where its greater resistance to abrasion might be a life saver.

I have used both in my time but on the Phoenix I have gone for copper which i believe will be more than adequate.

Cheers guys, exactly the answer I was after, guess I will be fitting the brake pipes this week then.

NO !!! -- actually illegal in many countries.

Use proper 3/16" Kunifer brake pipe.

But perfectly legal in the UK, and has been used by many people for many years,

However, kunifer (copper - nickel - iron = cu-ni-fe) is better by far, whilst still being workable. Avoid steel tube unless you have a really good flaring tool. Kunifer is the preferred material by people like Volvo and RR, I believe (IIRC).

I prefer Kunifer as I believe copper can harden & become brittle, Kunifer is much stronger but still easily workable

Use Kunifer if you can get it. It is slightly more difficult to bend than copper, but is more resistant to fatique.

Copper is real easy to bend but work hardens.

Steel is an absolute pig to flare as I found out trying to repair my daily driver.
