Caliper piston

[squabeggz]

Got a set of 199 calipers for nothing. Kinda rusty, so I'm seeing if I can clean them up and make them useable. Popped the pistons out (with a bike pump). The piston walls look clean and blemish free. The exterior (pad pushing) surface....not so much. Still useable? I would think so, but thought I'd check for other opinions here as well.

Yep you're good. Mine looked like that before I rebuilt them. I put some gasoline in a plastic container, then set those down in it for 10 minutes. I them took a wire brush around the lip. Cleaned it all up with some brake cleaner and they were a lot better.
