I've pulled my estate apart to replace everything that needs renewing or could do with it
I need all New brake lines but don't know which ones to get
I'd like braided as much as I can as it will be stronger

Does anyone know what size braided line to get?
I saved all the unions and fitting but had to bin the lines themselves

[Cooperman]

Best bet is to buy a complete brake line kit from Mini Spares.

Errrr.......really??????

[nicklouse]

too much braided can give a soft pedal due to "squirm"

 

flex hose moving under pressure.

I don't mean do the entire car with braided. I'm not that stupid
I mean rather than the crappy hoses that come standard I'd rather have braided there

I just need to know the size of the copper pipe so I can order some
And the size of the braided pipes

[Dusky]

Kunifer. Not copper.

I thought braided brake hoses where not suitable for road cars. By not suitable I mean they wouldn't get through an MOT.

[nicklouse]

they are fine for the MOT.

 

same size as standard. do you have a flare kit?

[ukcooper]

Kunifer. Not copper.

Braided pipes from brakes to the end of the line, Kunifer for the lines standard size 3/16 I think 

 but Kunifer is a bugger work with ..cause it Cupro Nickel Kunifer and the Nickel is bloody hard not like cooper..

I run standard brake pipe with goodridge braided hoses to the all calipers front and rear.
I run 4 pot kads on front and single pots kads on the rear.
Yes its for the road.
Brakes very well
No issues with M.O.T.
Goodridge hoses are as a set from all good mini suppliers
As is the brake pipe.
But get your self a good quality flairing tool and learn how to do single and double flairs.

They do look great I have to agree on that, but no stronger.

 

They are also difficult (ne Impossible) to inspect properly compared to the rubber types.

 

And when trying to diagnose a brake problem, you can't clamp a braided hose off without damaging it.

Thought about going braided between pressure control valve and Master cylinder then saw the cost. In the end got a 30' length of 3/16" 90/10 Cupro nickel (Did the whole car except for the front sub), and all the fittings for not much more than what the two afore mentioned braided hoses would have cost, bought myself a flaring tool, made a small former with a 9/16" minimum radius to bend the pipe around, made a few ******* ups, shouted few choice words, learned something relatively new and enjoyed the experience. In the end pleased without spending a shed load of cash.

I have a flaring tool and reamer
I just need to know what diameter the brake pipes are so I don't order 30' of the wrong size!

This is what I will be hoping to run. But it won't be goodridge hoses. It'll be braided line that I cut and fit myself to save a small fortune

There is only one size of brake pipe used on almost every car, whether imperial or metric. It is 3/16", which is very close to 4.75mm, within normal tolerances, (actually 4.7625 mm but it is not made to that degree of accuracy, that is only about half a thou different) so it may also be sold as 4.75mm..

 

As said by several people above, do not under any circumstances use copper. The British Standard to which copper pipes are made (if you are lucky and find that they were made to any standard at all) is not appropriate for brake pipes, and they have very inadequate fatigue properties. The very worst have inadequate wall thickness too, and are advertised as easy to flare. Possibly true, but even easier to burst.

 

Unfortunately there seems to be no effective restraint on selling unsafe products.

 

Don't be too scared of working with the Cupro Nickel. I found it to be easier than copper to form correctly, although you do need to apply far more force. Any decent flaring tool will handle it, but you may want a bending tool, which the likes of Frost can probably supply.

Did minis come from the factory with copper hoses ?
