Master cylinder brake pipe thread sizes

[boffer8]

Good Morning all,

Trying to find out what size the brake pipe fittings are that go into the standard master cylinder as i would like to order them before i pull the system apart.

I think 2 are one size and 2 are another (due to the residual pressure valves) and i think one of the sizes is M10x1.00, but not sure on the other, anyone help me out?

Thanks
Ben

Incidentally theres absolutely fukk all reason why theyre a different size.i was making new lines up and didnt have the bigger male union.so i stripped a spare master down and swapped the small end with the big end.kept all the internals same though.even theyre identical.

So they have 2 M10x1.00 and 2 M12x1.00 unions then?
