One question. After the pads were initially replaced was the pad wear indicator reset with the m/benz software because if not then it will show say 25% pad left when in fact you have 100%. Due to the fact that the m/benz epb [ebs] system uses the pad wear info to adjust braking across the axles this could cause excessive braking on the other axles when not actually required to even out the pad wear across the vehicle. The guys that changed the pads should have checked this [as it should be rest after every pad change]. Unfortunately not many places do because the equipment is expensive but it has to be checked. The pads in the pic were they sensed [wear indicators] and which axle were they from?.
