Cooper pipes are not illegal to use or supply, as with any part that is fitted to any vehicle particularly with regard to the brakes it is only dangerous if not fitted correctly. Copper pipes can fail if they are not secured properly, but then can many other parts fitted to any vehicles. Copper is supplied in the kits, due to its properties (being easy to shape), but still needs securing once fitted.

Thanks for your answers, in hindsight should have asked the original question slightly different. Will apologise for keeping at least two members up late last night ! Matter closed.

lol, No apology needed.

tommy13,

You have no way of knowing whether the fatigue fracture was caused by vibration, or by pressure cycling. Most likely, both contributed to the failure. Even if you clip the copper down tightly (not leaving it floating in mid-air as an alleged mechanic here is advocating), the pressure cycles as the brakes are periodically applied will make it suffer fatigue failure in exactly the same way.

i didn't mean to leave it floating just not against the under body or touching other pipes where it could vibrate and wear (but still making sure it is clipped in the correct places)

my boss has been in the trade for (give or take) 40yrs and never found a problem with copper (not pure copper ) brake pipe, E.G. its better to have harnesses but people still use normal seatbelts
