Brake piston?

Question

I recently cleaned my piston and piston seal on my Gs 450, didn't need rebuild but the seal was new, it just wasn't cleaned well in the seal groove, sits fine now. Anyway, can I reassemble the brakes with the piston dust gaurd off just to make sure the piston seal is sitting right and not leaking out around the piston. Will it work like that? I figure the dust guard would hide a sign of a leak. Will it hurt anything if I do that just to check it. Also my piston is cleaned up nice now nothing wrong with it xcept for a little something on the bottom, nik or chip. The caliper was kinda dirty but looks new now. Do i need to worry 'bout the little chip on bottom of piston. Can old fluid do that to brakes?. I bled everything really well and I'm sure I hooked them up but want to be sure. Cars I can do but with my bike, better safe than sorry. Manual just shows parts, not cleaning. I searched answers before asking this and couldn't find what I was looking for. New rider but mechanicaly minded

Sounds like you have done a correct job. I have cleaned many many brake caliphers over the years and very seldom are any new parts needed. Go ahead and assemble it completely and hook it up, also, don't worry too much about a little nick ( especially one at the bottom) I have reinstalled some pistons that were quite pitted from rust and they still worked fine.
