Although this is all very interesting i still can't get a decent flare on Kunifer and as a coil of copper (which i can get a good flare on) is a
damn sight less than a 'decent' flaring tool I am now thinking of throwing this Kunifer crap in the bin and getting a coil of copper.

Which is exactly why I did mine in copper,it just wasnt worth the hassle.

Im not gonna get into who's right/wrong, im not qualified for that but...
I used the kit in the pic below to do my escort's brakes for its MOT. I asked an independant garage (not supplying pipe or doing any of the work)
about Kuniffer and they recomended I stick with copper.
MOT station checked my work closely and OK'ed it without issue.
Included are pics of pipe used & it's info sheet, Is this plain copper or an alloy of some kind?
I would be interested to know as I will do differently in the future given sufficent reason to.
PS. I got even (not off center) flares with this tool but there were griper jaw marks on the copper pipe from the tool.

Same tube as I used Steve same flare kit,both for the locost and my daughters car for a brake reline when it failed MOT.
No probs at all,the clamp marks from the flare block didnt cause any hitches.
Problem I had using kunifer with the flare kit was it just pushed the tube through the block as I was flaring it, even though I tightened the wing
nuts with an adjuster.
The snap on flare block that I had some years ago was the same principal but was far superior..Lent it out to some Tw*t who never returned it.

I used the Clark flaring tool and Kunifer and had no problems apart from stripping one of the wing nuts. I got a brass one from the local bolt shop
and it's been alright since.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

If my memory serves me right Pete my brother in law who used to be the manager at the local machine fart told me they had changed the manufacturer of
the kit some years ago,and they'd had a load of returned items shortly afterwards.
Could be you have the decent one.
Cheers,
Bob

Look at copper pipe this way --- a Coil of 15mm copper water pipe freshly bought from Plumb Centre or B&Q is nice and easy to work with, but
plumb your new bathroom with it go back a year or two later and try alter in the pipes slightly -- you will find in this short time the pipe has age
hardened and is a almost impossible to give even a slight bend without kinking or splitting.

BS2871 = bog (!) standard general purpose copper pipe.
It is not just some states of the USA copper brake lines are illegal but Germany and" parts of Scandinavia" see this.

This is getting a bit boring now.
Plumbers copper in no way equal to the copper pipe used for brake lines or refrigeration its hard drawn copper usually for one thing and very low
grade,the flaming joints are usually soft soldered and is not made to cope with the pressures that a brake line would be expected to handle.
Read the label on the pic posted previously 3/16 will cope with 3100 lbs in sq, 1/2 1100 lbs in sq. this may give you a clue.
I dont doubt you it may be banned in scandinavia but we dont have winters 4 months long at temps that would freeze the rocks off a polar bear and
therefor have to throw more salt at the road than you do on your chips per square inch.
And as for your article the stupid tw*ts got more chance of being beheaded by his triumph heralds forward hinged bonnet than he has his copper brake
lines giving way,so I wouldnt be taking any advise off of that sad sod.
Cheers,
Bob

All copper pipe is soft when you buy it it both work hardens and AGE hardens.

yup, and silly or not, those little grooves left by crappy flaring tools are brilliant stress raisers, and look utterly shite.
I have had the daftest of items fall off my grasser due to fatigue due to it's solid mounted engine, copper lines would last all of 5 mins. The
rivets pop their heads off on a regular basis.
I may be nitpicking but that's why I binned my crappy old flaring tool!! Buy a proper one!!!!!!!! (you could even offset the cost by making
lines for those without the tool at a VERY competitive rate (preferably beer!!))
