Thank to all who replied.

O.K., after filling the brake fluid reservoir, I pumped the brakes and sure
enough I see some fluid coming out the back where the rear diff. is.
Actually I can hear the air pushing out when I pump the brakes.

Any BDTD on which brake line it is and/or ease/difficulty of R&R? I didn't
have a chance to inspect futher(I'm in a parking garage).
