Squeaking/Worn Brake Pads May Require Rotor Replacement Also on Mercedes-Benz CLS550

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).

Same issue. Major shudder when braking. Speed doesn't matter. Anything more than a light brake causes a noticeable shake in the vehicle.
Got this problem taken care of a few years ago by a local independent. The brakes would shake slightly but what I noticed first were the squeaky brakes in the cold mornings. Factory pads/rotors were installed and the shaking problem went away. The original rotors seemed to have been warped.
The braked squeal like a pig. I just also developed a strong gas smell emanating from the right side of the car.
