Problem Description and Possible Solution
Due to the size and material used on the brakes of these vehicles, the brakes may start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).

I had this happen for the first time after 10K miles. I took it to a different dealership and they replaced the rotors. All was well until the standard replacement time - in the last 10K, I've had three sets of rotors. I'm not convinced they have fixed it even now. This is just one of many problems I have had with this car. It has been a major disappointment. It will be my last M-B.
I have brought my car in for pulsating brakes 5 times!! I have had the rotors replaced 4 times and now my car sits at the dealer and they want me to pay for 50% of the replacement of the pads and rotors. The problem has never been corrected since I purchased the car and makes me feel very unsafe to drive the car because the pulsating is so significant and my passengers can feel it. I am very frustrated with this problem. I just got off the phone with Mercedes and am waiting to hear how they want to resolve this. I am a 50 year old woman who is the primary driver of this car. I don't drive the car hard and rarely am on the freeway in traffic or high speeds. This is my 2nd Mercedes and I LOVE my car, but this chronic problem would cause me to not buy another one. They are telling me that this is "normal" and that pads and rotors will cost 900.00 at the dealership every 10-12K miles!! That is crazy to have to spend that kind of money that often and to have to replace the brake pads AND rotors each and every time...
during the last check up I mentioned a slight brake chatter in the front wheels during any stopping. Today I took it to the shop in Seattle that sells and services Mercedes Benz E550. He called this afternoon and said it was not covered on our maintance policy. He said we were dynamiting our brakes or riding our brakes? Neither are true it is pampered and garaged every night with regular maintance. The bill and parts quoted was new rotors front and rear, new pads front and rear. I am confused we bought a Mercedes Benz because it was German built and designed. To me it right now is coming up a little short. Help me out was this a recall?
had front rotors/pads replaced and one year later already the rotors had grooves in them with shuddering/vibrating on braking, especially at the point before complete stop. I repaired the problem myself, and found one of the rotors was a bit warped as well. I decided the calipers were probably seizing, so I replaced the front calipers, rotors. Pads are still fine. Problem is fixed for now, but it seems like this may be a recurring theme, with rapid wear of rotors.
Front brakes squealing when braking at low speed, especially close to a stop. Went on for two years. I finally had the front brake pads replaced by Mercedes, at my cost (even though they weren't worn significantly) and that was the end of the problem.
