Banjo bolts for brake hoses

Hiya, I am currently upgrading my 1981 440ltd D-4 to twin front disk brakes. I now have all the bits which has been fun sourcing, except the extra banjo bolts for the brake hoses. It seems that there are two types, M10 x 1.0 and M10 x1.25. What is the difference and which one do I need? any ideas?

cheers,
Mick

M10 is 10mm diameter, 1.00 or 1.25 is the thread pitch.  You need M10x1.25.  You can measure with a gauge or just use a known size 10mm bolt and try to align the threads with the original banjo bolt.

cheers thats great
