2017 Base Cayenne Long brake pedal travel

I have a 2017 base. The distance the brake pedal travels before the brakes engage seems very long. about 1/2 way down. This is much different than the 10mm referenced in the owners manual. The brakes then work fine. Pumping the brakes once before braking has become the norm for a more realistic braking. The dealer and they said the brakes are within spec. But i'm not buying that. When trying to make subtle adjustments to speed it causes over reactions to get the car to react. Maneuvers such as parallel parking and an exercise in how fast you can slam on the brakes for a small adjustment. Driving in traffic always feels like your eventually going to roll into the person in front of you. Definitely will if your the tailgating type. Has anybody experienced this?

I have a 2014 base and after years of this annoying me I decided to try to break the car (while still under warranty). I spend a week doing bad things. Nothing different happened...... Untill..... I was stopped at a light. I did the double pump thing so the pedal was real high. Then held full max pressure on the pedal. After a few seconds the pedal dropped away. All the way to the floor. It felt like a blew a line. I didnt blow anything. The reservoir was lower, but not empty or even low enough to think that was an issue. But the pedal has been normal since. (almost a year). It has never done that fade to the floor thing again. I have tried. It never leaked. I am GUESSING that one of the pistons had been stuck since the car was new. Since your car is under warranty..... Maybe you should try pushing the pedal to the floor. I mean it, all the way down.
