Master cylinder leaking?

I was looking at a used '98 and noticed fluid leaking (or weeping) from what looks like some sort of secondary master cylinder on the right fork slider. There was just a drop or two hanging from the bottom of that unit.

Anyone ever seen that?

 

Having a drop or two hanging from your unit is not unusual.......

 

OH no you didn't, squirrelman!.............

 

A motorcycle master cylinder only holds a little fluid, so ANY leak would have it empty in no time.

 

I'm 90% sure it was leaked fork oil blown back onto the brake line.
