Well. Usually they stop the car. That's why they have as many stars as they do. But either Wagner changed their formula or they are fake because I've never had a pad that produces as much dust as these pads do. The previous pads were also ThermoQuiets and they didn't dust 20% compared to the previous ones. My bikes are a complete disaster in less than two weeks. The rear seats still have the "old" ThermoQuiets installed and are fine. Almost no dust.
