If any of the wheel cylinders are leaking, you will notice fluid at the bottom of the brake drums. Since they were new, that's probably not the problem.
Since the MC was rebuilt and there is fluid on the boot, I would say that is the problem. If it's seals correctly, you should not have any fluid on the boot after two years. Did you rebuild it or have it done? The cylinder has to be free of scoring and pits in order for the piston seal to seal properly. Pull it and inspect it.
Also check the lines for any visuable leaks
