I installed Rotex Gold pads about 10,000 miles ago. I installed both the front and the back with new rotors as well. When I first got it it wasn't making any noise at all. I'd say about 7,000 miles into it (when the weather changed) , it started to make horrible squealing sounds but that was eliminated once car was washed but not for long. Now with 10,000 miles there is no squeal even if I havn't washed my car in a while. So I'm a happy camper now!
