81 CB750K front brake caliper piston/seal

[kraptastic k]

Hey all,

I'm looking to buy or source the piston/seal for the single front disc DOHC CB750K that ran in 81 and I believe 82. Partzilla and other sites are showing this product as obsolete, and its replacement number refers to a caliper assembly. Mine is corroded and pitted and the seal is deader than a rug on Valium. I'll buy your NOS/gently used piston or take advice on where to find it.

Thanks,

krap

The sealing ring was correct, but the piston was far too small to be the correct part. I will try to document the difference and specify the correct part when I return the incorrect piston to partsnmore

Just an update

the 1982 cb750k is a dual piston caliper. maybe that's what you got instead
