Rear bowl(front brakes) overflowing

So I finally got my rebuild out on the road for some test driving. Noticed fluid leaking from master. Rear bowl for the front brakes is overflowing with fluid and leaking, the front bowl for the rear brakes was damn near to the bottom.

I'm going to the parts store to grab a new master...but any other ideas outside of that? It sat for a year or 2 unused so my thought is I probably have a bad seal in there?
