Some brake setups never go out of style-and when we're refreshing our ride, we trust Kool-Stop Disc Brake Pads for Hayes systems to bring stopping power back to life. Whether we're navigating wet switchbacks or easing down city streets, these pads deliver the quiet, consistent braking we need. Kool-Stop's organic compound blends in a touch of metal to strike the right balance between rotor-friendly performance and long-lasting bite. Designed to fit a range of older Hayes hydraulic and mechanical brakes-as well as select Promax models-these pads are quick to install and hold up under serious use. They modulate well, resist fade on descents, and help us ride with confidence in all conditions.
