I have this problem on my 08. It's the rear brakes that make the noise. Car only has 2200 miles on it. Seems to happen more first thing in the morning when backing out of the garage. I'm planning to mention this to the dealer when I bring the car in for it's first check up. I had the same issue with my 2001 S430. Dealer replaced the rear pads and applied some paste. The problem went away.

MB brakes are a bit sensitive for squeaking, specifically when first running off with cold brakes, even more if the brakes were wet when the car was parked.
One should use breaks to make the heat up well (not to glow red) and it would be good to "dry" the discs before parking at rain.
Next thing is this copper grease or similar at the right parts of the pads (of course this stuff should not reach the face of the pads and the stuff should handle high temperatures.
My W221 acted a bit, only when first reversing after the car had been parked at work and braking the first time. Using a bit more brake force makes it disappear and I have not heard it even if I have not applied the paste.
The W211s I've had both did that but the copper stuff fixed it.

S550
Thanks everyone. This seems to be more of a MB problem for me because I never had squeaky brakes with any of my Audi, Lexus, or BMW cars and SUVs. In fact, no car that has backed out of my garage has had squeaky brakes except for the S550, not even the Buick POS I drive as a company car. I'll see what my dealer says.

funny (not haha but peculiar) as all of my previous benzos had squeeky brakes EXCEPT my current 221 (2 yrs, 17,000m); it's as silent as can be. now i'm jinxed, i know.

Squeaky Breaks
All I can share is my experience with my GL 450 and my '08 S550. I had the squeaky break problem on both vehicles. First was the GL. The dealer went through the process of "baking" the pads and they still squeaked. They then changed the pads and the squeak was gone. I no longer have the GL but experienced the same on my S. I went through the identical process. All I know is once again, when the changed the pads, I no longer had the squeak. It's been about 3/4 of a year and not a single squeak.

The squeaky brakes are because of brake dust. I had the brake pads on my 07 S550 replaced (with just 6000 miles) , and they also applied the backing paste. It worked for a while, but then started squeaking again.
As an experiment after washing my car, I power washed the brakes, and watched the brake dust stream out of just every about every crack, including the rotors. So much so that the brake dust left an imprint in my driveway for weeks on end...
It goes without saying, that I didn't have a single squeak until the brake dust began building again.
It's real plain and simple... The German car manufacturers use pads that give off an excessive amount of brake dust, -- Take a look at alot of German automobiles where they don't receive a frequent cleaning regime, and you will see the nice alloy wheels caked with brake dust-- Something you just don't see on Japanese vehicles.
The only way to fix the squeak is to clean the brakes/rotors using pressurized air or water, or to switch to a different set of pads .

Occasional problem of various high-powered braking systems
Have never had an MB/AMG w/squeaky brakes (amongst dozens of new 550/600/63/65, etc over past ~10yrs)
Have had ?two of ?six new Porsche 996TurboS and 997Turbos w/squeaky (ceramic) brakes (one for entire 3K mis I had it; other started only after 12K mis; traded-in by ~15K mis)
Have had several new Ferraris w/ceramic brakes w/no issues w/squeaking
Often issue is prompted w/cars used heavily in low-speed driving; one solution is to do a few aggressive 80-0MPH decelerations on empty fwys to "cleanse" brakes
That said, my sense is best techs at best AMG/F/P dealers really don't understand why certain high-powered brakes have occasional squeaking...and others have no issues at all....
IMO, would rather have a high-powered braking system that works well in both dry/wet, w/excellent pedal feel, than any of the laughable brakes on cars like BMW, Lexus, Audi, Lambo, etc....but to each his own
