Alison,
As Ben pointed out, the brake booster can be at fault. And if it gets too
frustrating, you might want to take it to the pros. I've found that the
vacuum pump is the best. Another potential problem might be the master
cylinder. Had one that developed an internal leak, which yielded an
intermittent soft pedal, which felt like there was air in there or a
rupture. Never any lost fluid so I did a number of bleedings. It only
stopped with the replacement of the MC.
Cheers,
Fred Kuzyk
