14mm

Brake calliper pistons are 2 x 14mm?????
I would think more like 2 x 28

Are you thinking of the brake master cylinder?

If you own a vernier caliper simply measure it.

The master cylinder usually has the bore size stamped on it.

A ruler would likely be more than adequate unless they are using some goofy size like 29.37 millimeters. I've never seen anything like that.
