Piston in master cylenders

[JC T ONE]

Hi all,

can any one help me = I have dismantled both master cylenders, and accidently mixed the two pistons

They were put on different shelfs but one rolled out over the edge, and landed next to the other now I am unsure which goes where ?

The left one is a tad taller, and 100% flat on top.

The right one is a little shorter, and has a domed top.

Thanks

assuming youre talking clutch n brake....
the clutch piston diameter is 0.75" and the brake 0.7"

Hi & yes, brake & clutch.

Tried to mesure them - seem to be the same ? will try again to morrow.

Thanks
