I have the brake pulse when braking at higher speed on my E550 4Matic after only 5000 miles. I did everything just like other members suggested. The problem did not go away. Dealer and MB rep did not want to do anything citing it's not a performance problem. The car stops. Low miles and environmental (oxidation) condition were the causes. Calling Customer Care Service was a waste of time. I had a 2006 CLK 350 before. It had a similar problem. Dealer replaced all 4 rotors and 4 pads under warranty. I sold it before the problem starts again. A mechanic suggested to buy aftermarket rotors and pads with high quality. It will be costly! Replacing with factory parts will not fix the problem for good. After a few thousand miles it will be back. Any suggestions for this problem? Sell the car again? Then say good bye to MB for ever? Thank you for any suggestions.
