I am using the SRAM Rival eTap (new X). Usually, there is no problem when I use it, but whenever I ride downhill a little and apply the brakes, I hear a loud "whoosh" sound. I've already replaced the brake pads and lightly sanded the rotors with sandpaper.
Since other bikes don't make any noise, I don't think it's because it's too hot... Could anyone who uses SRAM brakes give me some advice?ㅎ
