2011 Mercedes-Benz GL450 Q&A

2011 Mercedes-Benz GL450 Question: Does a sensor light come on when the brake pads need to be replaced?

My 20,000 mi. service check light just came on. My tire guy told me that I needed new back brakes and that the rotors always have to be replaced with the pads on my car. I just took the car to Mercedes for the check light and they tell me that my front brake pads need to be replaced, but not the rotors. Who should I believe? -
