Brake Union Size ?

[JensenA]

I ordered standard M10 Male unions for the brake pipes on the front Brake Pedal Box. But they are not metric - anyone know what thread and size they are?
Cheers

Alan. Perhaps they are M10 fine ie M10 x 1.25 instead of M10 x 1.5. I know this is the case with alot of the Jap bike brake fittings.
just a thought mate. Mike

the standard for non metric is 3/8" x 24 tpi (teeth per inch) but I would be v surpised if they were this size. Not seen any new car come out with these on for years.

I've found the answer now.

3/8" UNF at the brake box, and the rear 3 way brake union, and Standard M10 at the 4 calipers.
