I agree with that. I would look for signs of the power
booster being wet or move the mat under the dash and look for signs of floor being wet. That's if it is leaking out. If you said your not losing fluid its internal. Like I said if you sit there and have a good pedal. Then it bleeds down most likely the master. If the pedal is spongy and it pumps up and gets hard usually then its air.
Sorry for spelling and grammar I'm doing this on my phone and I it doesn't word wrap. Its like one continuous line...got to figure why it does that.
