Hey all, I'm in the process of rebuilding my front brake, gonna be putting in a huge order with Len at the start of the new year (creating a parts list for everything i need is... man oh man PO's are a pain ). In cleaning/disassembling my brake caliper, i noticed a couple dents/scratches in it. Can anyone tell me if any of these are supposed to be there, or if the piston is still serviceable? I'm a student, so I'd prefer to not have to spend the additional money getting a caliper piston, but if i gotta i gotta. Thanks in advance!
