jza70 rear caliper piston size.

[fixeruperer]

hey all, I have to write a report on my car to get it engineered and i have tryed to look for the jza70 rear caliper piston size every where and i cant find it.
Reason for this is becuase i have r32 m/c and front 4 spot calipers and i need to know what size the jza70 rear caliper piston size is so i can change the bias valve to suit or if im lucky enuff i dont have to either way it all has to be in the report.

So if anyone has measured the piston size please let me know, help is muchly appreciated.

thanx.

Don't have measurements but it's the same as MA70 if that helps.

I raise one further question, unfortunately it doesn't help your thread. Why did you change the MC in the first place?

thanx anyway people's

i changed the master because i upgraded to r32 front 4 spots and jza70 rear calipers and i thought that the rear piston size was close to the rear of a r32 caliper and the MC has internal bias valve so it would be a system that should work and on the engineers report it would look better that to have 3 differant brake parts from 3 differant cars, now i only have 2 .
