Make sure you get cunifer (cupro-nickel), NOT copper. Apart from that, you just need the set to fit your exact model of Mini, as the pipe layout changed a few times.Cunifer is a dull greyish red and quite stiff, copper is bright and soft.

If they can't tell you what spec the tubing is made to, take your business elsewhere. Some suppliers are selling pure copper pipe with a bogus BS spec number, and others are supplying copper that is intended for air conditioning systems. Your brake pipes need to be able to stand very many pressure cycles, up to about 2000 psi, without fatigue failure. It needs to be stuff that is designed to be used in car brake systems. The pure copper that some supply is illegal in the US, Australia and most of Europe, but for some reason VOSA have not yet banned it in the UK.

Pure copper which may have a stated burst pressure of 8000 psi, will be much weaker at the ends after flaring, and it will not stand all that many prerssure cycles before failure. And, if not clipped down very tight, and allowed to vibrate, it will suffer even more fatigue damage, not due to pressure.

You can of course use steel (Bundy) pipes. Apart from the corrosion problem, which unlike fatigue can be visually checked, they are safe and cheap.
