Master Cylinders are designed to split the front from the rear braking systems, If it shows that it is wet where the master cylinder is mounted, it is probably leaking from the master cylinder itself. You can check to see if the power braking system is working, by pumping the brake pedal with the engine off until the pedal is hard, then start the vehicle, the pedal should drop, if it remains hard, then you have a problem with the power booster. I'm more inclined to say it is your master cylinder. The larger reservoir in the master cylinder is for the front disc brakes, the smaller reservoir is for the rear drum brakes.
Good luck,
