Mercedes-Benz 420SEL Problems

Squeaking/Worn Brake Pads May Require Rotor Replacement Also on Mercedes-Benz 420SEL

Problem Description and Possible Solution

The brakes may begin to squeak at about the 50 percent wear point. This is due to the size and material used for the brake pads and rotors.  The brake rotor surfaces become uneven, causing a lip to form at the outer edge. This will generally require replacement of the rotors when the pads are worn (pad life varies depending on driving style and terrain).
