Brake piston O-ring

[1982SZ]

Hey guys,
re-did the master cylinder on my front brakes and now the front piston has the lever going ot the bar.

Anyone know what size that O-ring is for the front brake's caliper piston?

TIA...

DO you have fluid leaking around the caliper piston that you can see? If not, sounds to me like you just need to bleed them some more.

There's a leak but I have not located it yet. Funny how the brain just jumps into a project! Damn, I gotta slow down....thanks.

Found the part # on Ron Ayers, for anyone else...59107-34020

Are the front calipers on those things two piece like others? In other words, do the two halves of the calipers bolt together? If so, may want to replace those while you're at it.
