Yes, this is true, at least for the 955 models.

 

Cannoli, based on your feedback on the brakes on your Cayenne have you followed the factory recommended brake flush every 2 years? I know that brake fluid can play a big role in how the pedal feel can be... and if you did do the brake fluid change maybe they did not bleed it 100%? I know the brakes on my 2004 seem pretty solid, might be worth trying another Cayenne to compare if the feel is similar to yours.

As for rotors and pads, once I need them I will probably go with the cross drilled Zimmermans and Hawk low dust pads. I like the cross drilled look I had on my 996.

David - very good point / suggestion. Just about two years ago, I purchased the CTT and had one of my local P-dealers do a PPI (post purchase in this case) and had the brake fluid changed. I'm due to change the fluid again.

My brakes don't have any of the "air-in-the-line" issues. It just requires more foot pressure that it should, but then again I'm trying to stop a vehicle with the weight of an elephant with the speed of a cheetah.

My reference point is mainly the MB sedans that I've owned, and currently I drive a Porsche-built 92' 500E. It has factory aluminum Brembo calipers (fixed - not floating like most BMWs) with 300 mm rotors in the front, and upgraded cast iron ATE SL600 calipers with 300 mm rotors in the rear. This car can brake, and brake well.

Here's my big issue with my current CTT brake set-up - one should be able to invoke ABS during normal driving conditions. My CTT does NOT activate the ABS during normal or panic braking conditions. Tires should be the limiting factor to braking, not the calipers/rotors/pads. The only time I've activated ABS was when I was driving DOWN Mt. Palomar (similar to Mt. Hamilton in the San Jose area) and all the weight was on the front axle.

Again, I'll said it again, "the Emperor has no clothes" and in this case Porsche new they had brake issues on the 955 CTT and that's why they upgraded the 955 CTTS brake system. Remember, the HP increase from the two 955 sub-models is only 50 HP - not that drastic (~10% in HP).

Thanks for the fluid change suggestion.

 

the hawk ceramic pads right??
I am thinking the same thing.....cross drilled zimmermans rotors and ceramic hawk pads...
thanks for the heads up !!!

 

i have upgraded to zimmerman drilled rotors---with pagid r14 pads----very sharp braking---almost 2 sharp---it throws me forward everytime i touch the brakes

 

Any idea were i can get these?

 

How about the EBC yellow pad ? Good or bad ?
