anyone know what thread unions go to what connections and what size pipe is used

thanks

Standard 'bundy' brake piping - but use KUNIFER pipe, it doesn't rot and certainly NOT Copper! Front end and master cylinder are 3/8" UNF thread - rear axle (for some mad reason) is 3/8" BSF thread.

i thought there is difernt thread between the flexi and normal unions

ie some course some fine?

is this right or are they all the same thread apart from wots been said

anyone know the exact lengths of the various pipes lol

go on i know someone out there will

Pipe lengths? See http://www.morrisminoroc.co.uk/index.ph ... ic&t=15239

kool thanx 4 that

Why not copper or copper alloy?

Copper work hardens, and can therefore fail, but I've yet to have a problem with the copper alloy type. I'd use Kunifer, but I find it very hard to make the pipes up as it's so hard, Must sus it out....

hrm ... okies .. I'll keep my eye on mine then, they are copper looking and very soft at the moment, so I'd assume some kind of copper alloy.

That's what the specialists sell too, so I wouldn't lose *too* much sleep over it

Copper is perfectly okay to use. However there is copper and 'copper', ie pure or poor. Go for British made pipe from the likes of Automec, very good quality and reasonable price.

beware pure copper -it work hardens !! Copper 'alloy' may well be kunifer, cos that's what it is (CuNIFe) - which is the recognised best standard for long lasting brake pipes.
And yes - the flexi to the rear axle is a strange beast with 3/8unf at the pipe end - and 3/8" bsf (which is coarser than unf) at the T end on the axle!
