Just pick up my mercedes and the brakes are solid. I should have asked for the olds pads to see if it really is the problem. The ABS sensors light still on the dashboard after driving. I asked the owner about the ABS sensors whether is it really necessary to have those on. His respose was the only thing the ABS sensors does is to let the driver know that brakes pads are getting low in traction with the rotors and beginning to wear out and needs to replace the brake pads. Right now, he said I really don't need the ABS sensors since the brake pads are new and I drive less than 100 miles a month. Any comments?
