This happened to me a couple of months ago. I started out just fine...drove 5 miles to Wally World..came back out drove off to Carquest for a light bulb..all was fine...got in and tried to drive off and the pedal went to the floor !!!!! I pumped it a bit and partial brakes came back..got back to the RV park a couple miles away and the brakes were just fine. I found no leaks..the booster is fine..fluid levels are fine...I dunno what happened. This was all at sea level. Since then no problems.
Now, had this happened to you AFTER you came back down below 6500 feet, this might suggest air getting past the seals...we had this problem on pressurised aircraft, when at FL41 the pressurisation air forced it's way past the o-rings in the pedal cylinders..oddly enough the same cylinders used on one of our other models never had a problem, but they could only go to FL35.
Hmmm.

I've been driving Mellow Yellow around a bit lately. I just returned
from a four-night camping trip (without Mrs Squirrel, alas, she had a
conference in Louisiana to attend) up at Big Bear Lake, in Southern
California. Thing about climbing up to camp at 6,500 feet, is that one
must return to a lower elevation when the trip is done. This requires
going downhill, for a considerable distance.
While trundling around the lake, exploring the area, I was surprised a
couple times by the brake pedal going to the floor. I could brake if I
pushed a bit, and could pump the pedal up for normal operation if I
wanted to. After exhibiting this behavior for about five minutes,
everything returned to normal. But it was disquieting: when one is
expecting a long downhill in a couple days, any change in behavior in
the brake system is cause for concern.
Obviously I did not plunge off the side of the highway into a deep
ravine and die a horrible death of screaming metal and fire, else I
would not be writing this, showing my stunning lack of knowledge about
things automotive. The brake system performed normally the rest of the
trip and brought me home safely. Mrs Squirrel will be pleased, I reckon.
Before I take her out for our next trip together, though, I bet I better
have this mechanical issue put safely behind me, so . . . what to look for?
