Here we have a complete brake bundle of Hayes Dominion 4 piston brakes in either black or bronze with the otpion of adding rotors and mount adapters.
Hayes were the braking champions back when I was racing Downhill in the early and mid noughties (I know, I'm that old). Hayes Mag's and HFX-9's were known as the best all round brake on the market with great power and reliability. Ever since then I wished they would return to their best and with their new Dominion brake they are definitely back at the top of the braking game, this time with far better modulation.
Dominion's master cylinder is factory tuned for the shortest dead stroke possible and a crisp bite point. The Dominion A4 caliper utilizes four pistons in the most structurally rigid design possible. It features a cold-forged caliper and KingPin structural pad retention bolt that increases stiffness.
With a motorsports-inspired Two-Stroke dual port bleed system, industry-leading DOT 5.1 fluid and Kevlar hose, the hydraulic system is engineered for ultimate performance across all temperatures and easy maintenance.
Dominion A4 features the proprietary QuickBite² system for fast and consistent burnish, coupled with our D-Series rotor to manage the heat with less braking noise.
