My GS350 F Sport with 50K miles makes a very high pitched squealing noise at stop. It doesn't make any sound when the brakes are applied or while decelerating. Only at stop, maybe the last 10 -15 feet. It is very consistently happening every time. Whether the car is cold or been driving for a while. I had brand new ceramic pads installed and nothing has changed. Still a very loud, high pitched squeal at stop.
