They are quiet and have much less brake dust, the dust formation is hardly noticeable. Some users have reported that the brakes are less effective than stock. I also changed the brake lines to stainless steel when I installed these pads and I haven't noticed any reduction in brake feel. After installing these pads, I hear a slight metallic clank when braking in reverse for the first time after moving forward, which is due to the pads moving slightly. It also happens on the first forward brake after I brake in reverse. After the initial noise, they don't do it again until they change direction. Earlier pads didn't. I am very satisfied with the product and would buy it again.
