Failed Brake Booster Vacuum Pump
My car is:
2011 997.2 GTS with 58K miles, PCCB Brakes daily driver that I purchased new in 2013....maybe half a dozen HPDE days over the last 4 years in beginner/ intermediate groups.
My car is at the dealership right now after being flat bedded there on Monday night. The diagnosis which I just received a moment ago from my technician is a failed vacuum pump....so I can tell you exactly what happens from my first hand experience!
It's scary as hell.....without any warning or indication of any type, my brake pedal became hard and completely ineffective.
It was as if someone had magically placed a brick underneath the pedal!
It would have been 100% catastrophic had I been coming up to a stop light or approaching a sharp corner or attending an HPDE or slowing on the freeway for a Jam....ie- any type of typical driving event that requires braking.
There were no indications of leaking oil on my garage floor or warning lights, or noises or anything that occurred before, during or after the experience that could have alerted me to the problem.
I wonder how many have perished as a result of a vacuum pump failure? There would be no indication at all after the accident of an issue with the brakes as there were no codes of any type. The brake pedal never relaxed even several hours later (waiting for tow truck)... it was still as if the brick under the pedal....so it was no like a come and go "temporary" issue... it was a permanent loss of braking capability.
The e-brake worked fine... but obviously only works on the rears, and it required a moment for my brain to process what was happening....it felt like an out of body/surreal experience.
I had no idea something like this could even happen!!! I know mechanical failures can and do happen to automobiles---but this was shocking!
Thank God when it happened I was on a back country flat road surface, and had a safe parking lot to pull into.
I am feeling extremely blessed, and have a newfound sense of vulnerability that had never been there before. I am curious to see how I feel about my car when when I come to my first stop light stop after it's fixed

Near death experience
Same thing just happened to me. My girlfriend called me to come back home and get something before I was about to embark on a long, traffic heavy journey. I turned around, and as I approached the house, I had no ability to stop. It could have been a disaster. I'm so lucky she called.
