are brake master cylinders the same as clutch masters?

[waynos]

just wondering if clutch master cylinders are same bore size as brake ones?
not sure what sort my clutch one is
its not fc
can i use a brake master for a one tonne clutch in an aussie 4 speed?
the pedal is really heavy
could i possibly use something else to make it lighter?

 They are the same size body. The drum brake master has a one way check valve, but is removed for disc and clutch applications.

cheers

thanks scott,
funny i just spoke to my old man half an hour ago before checkin this
he used to be a brake mechanic,
and he said same thing.
when i was trying to get a kit yesterday ,dude told me they were different
thanks for your input.
now how can i change masters to make it lighter?
would smaller bore make it lighter?
didn't ask dad that.........
