A pedal that goes to the floor, and only firms up after some vigorous pumping
is the classic case of air in the lines. When the pedal starts firm, and
then slowly sinks away, it's caused by a bad primary seal on one of the
master cylinder pistons. When this happens, there will be no fluid loss.
The fluid that bleeds past the primary seal goes back into the reservoir.
