To clarify, I am the original poster and it was not dust that was bothering me. The actual discs would not be kept clean with HPS. I am not sure if it was pad deposits or what. I also was never impressed with the stopping power and this is my second complete set of HPS pads. So, I have replaced the rears with Axxis Deluxe street pads. They were almost 1/3 of the price and stop every bit as well and possibly better. I just got them on, so I do not want to pass judgement yet.
