Leaky Front Brake Master Cylinder
 

I just purchased a gently used 2009 KLX250S from my local dealership (extended warranty until 2013) and the brake fluid resivour is leaking(weeping). I checked the fluid level and it seems to be fine. There also seems to be weep holes which seems very strange to me. I know brake fluid can be corrosive. Does anyone have any idea what could be going on? Your input would be very helpful and appreciated.

Thanks, Brian
