[s-cars] No brakes

See my earlier post about rear flexible lines. I bet the rubber covering on
both rears is torn, the liner on both sides is bulged, and one side is
leaking. At least that's what I found. With parts and tools in hand, figure
about an hour, perhaps as much as two. Of course, it took me and my trusty
friend (who shall remain nameless, since the delays are my fault, not his)
close to four hours...

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).
