One single part number for both front and rear brake (180cm hose)

Introducing the all-new, Stealth Dominion, our award winning Hayes Dominion A4 brakes are back – 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 Ø17mm 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.

Available in SFL (Small Finger Lever) - ergonomically tailored for the smaller hand.
