The Triumph Dolomite Club - Discussion Forum

We had our brake line discussions a few weeks ago about to copper or not to copper but just reading a post in the resto sections there's a nice example why not to us the copper.

It's crazy that people use copper still. Kunifer is only marginally more expensive.

Never use Copper, no matter what anyone says.

Under the correct conditions, it work hardens and breaks.

I once spec'd copper lines on an HGV system I was designing and when the Foreman came in with them, he threw them up the office and told me to order Kunifer.

Working on Terrier and Warrior a few years ago I found a Rolls Royce drg from the '60's (Bulldog?) speccing Kunifer, so if that's what the Military have always used, that's what I'll do.

Copper will suffice, Kunifer is what should be used to be safe.

Ok, I am converted.
This shows evidence of an old copper pipe that has suffered fatigue when the fitting was undone and then re-fitted to a replacement flexible pipe. I view copper pipes as 1 time use only - you cannot refit them. Next replacement on my car will not be copper.

Similarly with nyloc nuts - I believe they are 1 time use only also ( awaits barrage of opposing views...).
