is the size of copper break pipe 3/16 used on aseicento, looking at replacing them all round!

That'll do.

Try and get some cupro nickel pipe such as Cunifer, the pure copper stuff goes brittle over time and causes problems.

Yeah, but I think the stuff people refer to as "copper" really is kunifer.

Generally, if you order copper brake pipe that's what you get - nice, shiny stuff that's soft as shyt.

Soft is good -- it's embrittlement -- age hardening -- that can be an issue.

Which you don't get with kunifer.

You'll get it, but much later. Well supported, copper should be OK. Fit it as though it were steel, and you're likely to get issues.

Whatever, this is getting boring now.
