Slowing down and stopping during an all-out descent on your mountain bike doesn't have to be scary. With premium-quality hydraulic disc brakes, you'll have all the confidence you need to tackle the sketchiest hills. The Hayes LTD Edition Dominion A4 Brake Kit has been developed for the rigors of DH and enduro riding. It is designed with a specific lever pull curve to balance on-demand pressure modulation, providing firm engagement between the pads and rotors. The brake includes two specific pad brake pads, intentionally developed to be paired with the new D-series rotor for fast, consistent burnish, predictable friction rate, and consistency across temperature and speed conditions.
