My brake pedal finally succumbed to this well known failure a little over 3 years after manufacture. In 2014 there were a number of reports of brakes locking on completely (and much earlier in their car's life) but in my case it seems to have been a very gradual process that was difficult to detect until extra "engine" braking became evident in the last week when coming off the throttle.
Whilst the Porsche service document attributes the problem to "high temperatures and high humidity" my case would suggest age of vehicle is also a factor.
So in addition to replacing the bushing, I had to replace front disks, front and rear pads (replacing those that had done around 2,500 miles) and rear caliper piston covers, all very irritating because had Porsche made this issue a recall in 2014 and not a "replace under warranty if owner reports problem" then fixing it would not have been so expensive.
If 981 Cayman and Boxsters (probably 2013 - 2014 manufacture) have not had the new part fitted, I'd recommend members get it done as a precautionary measure even though Porsche still insist on brake "failure" before doing it under warranty. Porsche allow 1.5 hours for Centres to do the work and the part costs £8.50. The relevant service document is "WM 460855"
