Hayes Dominion, our award-winning A4 brakes available in Stealth Black or Bronze – adding even more ways for you to stop!

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 SRL maintains all the power and feel of our proven Dominion A4, and accomplishes this using a specifically designed smaller and narrower brake lever. Dominion SRL can be used in conjunction with either our Dominion A2 two-piston caliper or our Dominion A4 four-piston caliper. With optional lever sizes and two caliper choices, Dominion from Hayes Disc Brake now offers a brake that's ideal for your application.

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.

SRL (Short Reach Lever) - ergonomically designed for the smaller hand or short reach level positioning.
