pretty sure its 3/16 as I just looked at me flaring tool and it goes straight through the 1/4 hole but fits nice and tight in the 3/16 hole

old tread i know but was looking for brake size. found the tube size but what screw niples should i order ( i used all the one's i had on the previous mini and never looked at what they wore.)

edit: should i use classic copper pipe or the modern cunifer (copper nickel mix) for the tube's?

You mean the brake unions like this?

http://minispares.com/product/Classic/Brak...k%20to%20search

Usually they are 3/8 UNF, brake limiter fitted from the 1980 on uses M10x1. In some older master cylinders (yellow band) they used something bigger for one of the sections, but I can't tell now whtehr it was metric or not.

Depends what exact brake components your using. Minis used a mix of 3/8unf and M10x1 fittings over their life span so either check what you need or get a box of both.

Be careful too! its easy to screw the wrong threads together.

I would always prefer kunifer, but copper is easier bent and worked with, especially if your flaring tool is less than great

speed didn't kill me, but taxation probably will

Okey. I know what ill use for clutch but still need to deside what brake pump (had to remove the servo so need to go rugular...)
The tool isn't that bad i have to press them by hand but it works very well.
