[FONT=verdana,geneva"] [FONT=verdana,geneva"]So...lets summarise.....these brakes definitely do not do what Porsche originally said they would...ie " last over 100,000miles and designed for extreme use on the road and track".....Alcon floating Steels are better brakes(amongst others) at a small fraction of the cost of replacement PCCBs (at approx £5,000 each disc+pads).....there is some inital lack of performance of the PCCBs in the wet...which has badly caught out some experienced drivers...and its seems that you need to replace them at around 12,000/15,000 miles....they are a bit lighter..but not many drivers can tell the diffence in weight on the handling...the new generation PCCBs as fitted to the 997 GT3 cup racers are being changed after every race by Manthely Racing....and if you drop the car into a gravel trap the dics can be ruined.....am I missing something or are they overexpensive and not worth the trouble....actually even leaving cost out of it (quite difficult to do as a complete set can be well over 25/30% of the value of the car)....they still arent up to it!!![FONT=verdana,geneva"]


 
Well, there are two sides to the PCCB debate.

All the top model road test cars seem to have them, the press keep praising them, latest specs are said to be lighter, more durable, better cooling, better protection, slightly different f/r brake bias, etc.

With the claims of long service life, superior retardation, no fade, unsprung weight saving, no corrosion, no brake dust, etc then many people will still choose to spec them, in the confidence that any early issues have been resolved.

If they live up to expectation they are a bargain. If not, swap to steels.

I'm sure they will perform on any given trackday with aplomb, but how many of the press have actually experienced them over a "long term test" which is when most of the problems rear their ugly head...
 
I agree...great whilst they last - except for the first few stops in the (very) wet...the trouble is they just dont last and are horrendously expensive to replace....they definitely don't fade they FAIL!!! and once the discs wear there is a huge amount of dust as the pads are ground away ...even Porsche say that new pads can be destroyed in 120miles once the disc has failed...the pads arent cheap either!
