 So I shut it off, turned it back on, the whole rest of the way down there and back, it never did it again. If it's got a problem with the ABS control unit and it's shutting the inlet valves off, it would do that. The pedal would be hard as a rock, and then if the ABS went off, then it could release it. So it sounds like I'd be looking that direction to see what's going on.
