fluid

My RC Cup came inside of his wooden box with some brake fluid spots on the bottom of the case..... nothing mayor... after a few trackdays one morning the rear master cylinder started leaking.... So I got a used master cylinder on ebay and now is doing the same.... Anyone else had that problem...
