Keep, Rebuild or Toss? (1 Viewer)

[82much]

I want to ask the community about what would be best. I have a old Brake Booster, Fan clutch (looks like green hub) and calipers that all went bad and were replaced by after market parts. I haven't had an issue with the aftermarkets but wanted to know if I should just keep these OEM parts and rebuild them (is it every worth the time and money) or just toss them out?

What say you?

Calipers are worth rebuilding if they are not rusted or pitted inside. Really easy to do.

Fan clutch. Seems like a lot of people drain and refill the oil to bring it back.

i know nothing about the brake booster.
