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.
