Doesn't sound like the problem I had - in my case the brake pedal went rock-hard temporarily, so no possibility to get it flat to the floor. Perhaps in your case there was a lot of air in the brake lines?
willr: Your description strikes a chord. All my weight was on the brake pedal and it was 'solid' like a rock, there had been no progressive resistance, it felt like flat on the floor and no feedback (you can generally feel the ABS and PSM pumps working through the pedal) through the thin soles of my driving shoes.
I am still surprised that they specially bothered to phone me up on my mobile to re-book the course.......... Perhaps there was something up with the car?
Hope my Cayman never exhibits this trait............
PSM - Porsche Stability Management
While it can’t overcome the laws of physics, the revolutionary Porsche Stability Management (PSM) system does lend an added degree of balance and control to the Cayman’s mid-engine driving dynamics, inspiring surefooted confidence in corners and extreme situations.
A standard feature on the Cayman and Cayman S, PSM continuously monitors steering input, road speed, yaw velocity and lateral acceleration to calculate the actual direction of travel. If the car begins to steer off line, PSM instantly intervenes with precision brake inputs on individual wheels to help bring the car back onto the driver’s intended path.
If braking alone isn’t enough to correct the vehicle’s cornering line, PSM then calls on the Cayman’s engine management system, adjusting engine output as needed to help stabilize handling. PSM can also compensate in an instant for mid-corner changes in load resulting from deceleration or braking. When Sport mode is selected with the optional Sport Chrono Package, PSM’s threshold for intervention is raised, allowing for greater driver involvement. If you prefer driving without automatic PSM assistance, the system can be set to standby at any time. In this case, it will only intervene under heavy braking, where both front wheels exceed the ABS threshold.
For all of its technical ability, PSM goes virtually unnoticed in everyday driving situations, preserving the Cayman’s natural agility.
I also experiened what I presumed was brake fade at a recent trackday. Foot flat to the floory and nothing. Took 2 or 3 pumps to get a result. Pulled in on that lap, gave it a rest, went back out and everything was fine. I was probably out for about 20 minutes with some reasonably heavy braking.
Very odd.
I just had the same experience on my sixth track day with this car. I flushed the brake system but on the second track day after that, the problem reoccured.
Does anyone have any insights? It isn't a cooked brake fluid issue.

The Issue IS known to Porsche......... It is a function of the PSM/ABS (PorscheStabilityManagement/AutomaticBrakingSystem) and occurs when we drive at the limits, and use 'Trail Braking' techniques - not features known on road driving.........................

I trail-brake on the road all the time, but never to the same degree that you do on the track.
Howi, you know how they always say "brake in a straight line, lift off the brakes, then turn into the corner"?
Well trail-braking isn't that.......
You turn in as you are lifting off the brake. It keeps the weight transfer over the front wheels and gives you better turn-in.
An instructor said "Have your hands at Quarter-to-three. Then imagine a string tied to your hands and the brake pedel. As you turn the wheel and one of your hands goes up, it lifts the brake pedel up." Basically as you turn in, you lift off the brake pedel.
jimmyd, I would go and look Brake issues at track
There is a lot of information in that thread about various track/brake issues.
Jack & Karel
Thanks for the info. It's interesting that there are two distinct brake problems, which are two too many.
I trail brake(and don't intend to change), but it will be in a different car. It's too bad because I really liked the way it handled, but I can get a C6 Z06 that I can feel safe in.
