Caliper Piston sizes?

[damo666]

Hi,

Just wondering if someone would know the piston sizes for the following calipers?

- VL Commodore front Caliper (NA type)
- VL Turbo Front Caliper
- VL Rear Caliper
- R31 Skyline Rear Caliper

Or, if you could point me to somwhere that I can find the info.

All single piston Commy fronts VB-VS are 2 1/8".
All commy rears for solid disc up to but not inc VT are 1 1/2"
R31 rears are 1 1/2"

Great, thanks for quick the response Dattoman.

In that case, any ideas why the VL turbo/V8's use the bigger 1" Master?
Just for a better pedal feel perhaps?
