Planet 9

Hello,

I have Cayman S 2007. Just bought it in mid Feb. with 11,000 miles.
I modified the suspension, brakes, etc…, but it is not important.
I mostly use it for tracks from VIR to W.Glen. It happened at the Watkins Glen when I pit after a session and the car cooled off slightly. I seat in the car with ignition off and pressed the brake pedal. To my surprise the pedal easily traveled to the floor. I started pumping the pedal and it became firm again. It happened that...
