loud brakes
I have brand new 991 with 200 miles. At every stop sign or red light my brakes make loud noise. I have tried going fast and slamming on brakes. Does anybody have any other suggestions? thanks

Already covered a bunch of times.
It's a performance car with high performance brakes. Noise is the compromise.

Lex is right, its a situation where the most high performance brake pads are also the most likely to squeal, so Porsche uses ones a little less high performance and a lot less likely to squeal, but its just not possible to eliminate. Squeal is caused when the pads bite, slip and bite again, typically a couple thousand times a second which is why we hear this ~3kHz squeal. You might ask your dealer about chamfering the pads (bevel the edges) or try anti-squeal adhesive, but really, no guarantees. The only sure fire cure is to spend a lot of time at the track. The more you use your brakes the more you'll appreciate them and the less you'll care if they occasionally make a little noise.

If there's one thing we can learn from all the links Lex, I sure hope it is the lesson that worse, much worse, than brakes that squeal like Ned Beatty in Deliverance- worse even than brakes that squeal like a NY taxi- are "breaks" that "squeak". Squeaky breaks are the worst.

As for the brakes, the solution is to run around town on Pagid RS29s for a while. Race pads on the street are so noisy that they make your German sports car sound like a garbage truck or city bus. And I love it! Then switch back to the OEM pads and the little bit of noise will seem minimal.

I think it's an order of magnitude of 8-10 times more for PCCB Pads/Rotors than Steel. Steel should be less than $2k and I've heard PCCB as much as $15k to $18k. In Canada the rotors alone are over $3,100 each.
