The Dominion four-piston hydraulic disc brake 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, and optimized for the world’s most demanding conditions and riders.

  • Low-effort lever input, coupled with high-fidelity power output for optimum braking feel and control
  • Pre-bled and assembled with Hayes K2 hose: The stiffest hose possible for maximum power and control transmission
  • 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
  • Both pad compounds are included: Semi-Metallic T106 (standard) and Sintered T100 (wet conditions)
  • D-Series rotors, caliper adaptors and bleed kit sold separately


NOTE: These brake levers can be run left or right. The only difference between front and rear is brake hose length, 1800mm for the rear and 1000 for the front. The "front or rear" option has a 1800mm hose.
