Looks like it is leaking from where it is bolted onto the brake booster. My question is do you get a new one or can I rebuild it? If new, any good experiences? Thanks for your help!

Yes, you can rebuild, buy a rebuilt one, or buy new. Lots of option. I usually just buy remanufactured with lifetime warranty but thats just me.

 

I would buy it new. I have got re-manufactured ones before that have been bad, and new ones are not that much more. Rockauto.com is usually the best deal.
