Bespoke brake pipe service?

[thefarmer]

Can anyone recommend/know of a company that can make up a bespoke brake pipe?

All I need is a bypass hose (shagged servo..and yes, one day I'll buy a shiny minispares one), but I can't really justify having to go and buy 25ft of pipe, a pipe cutter, a pipe bender, a flaring kit, unions just for this one small job.

It's annoying, as I used to fly about without a servo (and actually preferred it), but then binned the blooming pipe that I now need.



Any suggestions?

thnx

Why a company?...

Many of us here have flarers etc.
I have a couple of flarers, a selection of brass ends, some copper pipe,
but NO "bender", I'm straight...

What length is required?
What material pipe copper/cunife?
What material ends?

What is your location (please update your profile)?

Hi Ian,

I didn't want to be seen as presumptive...although after a quick web search, there doesn't seem to be anything obvious as far as offering this service.

I will do a final measurement tonight - I thought it was 45 cm, but will double check

No benders needed...i can probably find a bender up here
Material = Copper
Ends = 2 x male 3/8' UNF

Location - profile updated, but its' Dunfermline, FIFE.

thnx,
Ben

Hi Ben,

I'll do you one just let me know the length.

Just PM me the details & your address..

I strongly recommend the use of Kunifer (90% Cu, 10% Ni) instead of copper. It is almost completely corrosion resistant and is hard enough to withstand accidental knocks. Copper corrodes (verdigris) and is too soft especially in its annealed state.
Just saying.

I would gladly pay a fellow mini enthusiast who can make me the brake pipes to / from a servo for a MK2 S. I bought all the equipment but cannot bend them into the right shape. Any offers?

pm sent to you cheers Brian.

Luckily we have a Mini spares business here in Australia that makes all the brake pipes using quality materials and fittings, and the original factory engineering drawings and BMC Standards documents as a reference. They fit without the need for further twisting or bending. MKO also has a lot of genuine New Old Stock parts acquired when BMC/Leyland Australia closed down in the 1980's.

when I ordered some brake pipe from Brake line Factors ,I asked about the suitability of cooper ,they said that this is just about all they sell to garages in Sheffield for mot brake pipe changes ,and that it is specifically made for this? .
I can see how it being soft it would not be suitable for motorsport , but on a road car?. as for corrosion ,its going to out last the steel originals by miles ,isn't it?

I think the softness is not really the issue. Copper work hardens and then cracks where it hardened the most, which is usually where the flare is put on.

Short runs of pipe are the worst, so some think they can get around it by adding extra length in a coil (this is common on the capillary temperature gauges as well) but the point where the metal has been most stressed is by the flare and this is also where it is clamped.

The nickel in Kunifer and Cupro-nickel pipes gets around this.

As far as I can recall, copper brake pipes were an MOT fail in the 80's. Not sure if it has changed though.

Are we talking about two different alloys here, CuNiFe and "Kunifer"?

The CuNiFe being:
Cu = Copper
Ni = Nickel
Fe = Iron
The letters being the chemical symbols for the elements used, as per
the Periodic Table of the Elements.

https://en.wikipedia.org/wiki/Cunife

I was always under the impression that the non-steel, non-copper brake pipes
were made out of CuNiFe...

Should the question here really be:
Steel vs. Copper vs. CuNiFe vs. Kunifer - Which should be used?

Is "Kunifer" a trade name, and does it have, or not have, iron in it?

Ian

[Nick W]

so if this meets BS standards for brake pipe ,what exactly is it ?

[mk1]

I believe that Kunifer is a Trademarked name & the alloy used is indeed as above.

M

[smithyrc30]

I believe Kunifer is a trade name as is Cunifer. They are called Copper Nickel alloys and the common designation is 90% copper 10% nickel.

However they all pretty much conform to the C70600 standard which quotes the alloying elements as:
Nickel (Ni) 9 to 11%
Iron (Fe) 1.0 to 1.8%
Manganese (Mn) 1.0%
Zinc (Zn) 1.0%
Balance Copper (Cu)

The name used for the alloyed elements is Cupro-Nickel.

They are fitted standard to Volvo, Rolls Royce, Aston Martin, Audi and Porsche. Plus some others...

You may well end up with 50 personal messages to answer,
so it might be just as easy to post your own views on this thread.

If there's anything incorrect about CuNiFe and the name/composition,
I'd be glad to have some better information. Admittedly, I provided an internet
link, but I knew the basics of CuNiFe before the internet was even invented...
