It only appears to be coming from the bottom of the reservoir.  It's
actually overflowing from the top.  Mine has done this a couple of times.
My mechanic, "They all do that.  Don't fill the reservoir too much, and
allow for fluid expansion."  I have found that relieving the system pressure
by pumping the brake until it's hard will prevent this if I know I won't be
using the car for awhile.  I think it has to do with the check valve to the
bomb sticking and causing reverse flow out through the reservoir.  HTH.

BTW, I have a new bomb on my car.
