2015 MB E350
Moaning while braking
Posted this in W211 in error. Thanks to person that corrected me.
2015 E350 with original pads and rotors at 28K miles. Recent used car purchase from Lexus dealer. Since getting this car in July the brakes moan as brake is applied coasting to a stop. Finally took to a MB dealer that reported issue is caused by rusted rotors. The rust is on the inside of rotors Dealer suggested rotors could be changed, but still a lot of life remaining if I could live with the moaning. One representative suggested dragging on the rotors to clean off the rust. Apply the brake with one foot and accelerate with the other foot to drag the rotors thru the pads, to hopefully clean up the rotor surface. Are there better methods to clean up the rotors? Spray on cleaners? While shopping for this car I test drove other E350 sedans and wagons and several of them had the same moaning brake issue. I know rusty rotors are a problem for all cars. But is it more prevalent on MB's for some reason? Stoopid me for not having Lexus dealer fix it before I purchased.

Actually by dragging it might clear up the rust. I have seen a lot of MB cars with rusty brake rotors. Mine are like new but then the car is rarely out in the rain. I have heard that you can use a Grinding disc to clean the rotors but I have never done that. Sorry I could not be of more help.
