Thank you Jack for posting this response. I always assumed it was a vacuum issue that caused the hard pedal. This explains why the pedal goes back to normal without letting off the brakes. I have found that what is described does not significantly change my braking distances or lap times on the rare occasion it happens (once or twice per weekend).
On the other hand, I have experienced a phenomenon where the pedal gets soft and the car does not decelerate significantly. I have not experieced it in over a year come to think of it even though my lap times are decreasing. I even had a pro driver experience this phenomenon and had to take the escape road. It seemed to be the worst when I ran on Porterfield street pads.
Unmodified brake system by the way for me.
