Frayed,

Thanks for the info. From what I know of the ages of the vehicles with PCCB it is probably the first generation.

Let us hope they continue development to bring the price down and solve any other issues (such as the cooling one you brought up) which may appear.

For the price of them there seems to be little bugs which come up...as long as Porsche continues to warranty them, and as long as people are prepared for the occasional worry/inconvenience. I have never used them but I have been tempted. For all accounts and from several sources (Porsche and others) they are outstanding brakes.
