Making power is easy. Making power with the right feel, that was Hayes’ challenge. They did this by creating an all new system.
Dominion’s master cylinder is factory tuned for the shortest dead stroke possible and a crisp bite point. The Dominion A2 caliper utilizes two 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 A2 features the proprietary QuickBite² system for fast and consistent burnish, coupled with Hayes’ D-Series rotor to manage the heat with less braking noise.
Crosshair Caliper Alignment System dramatically simplifies caliper installment and alignment.
2 piston system for sufficent power and weight savings
Dual caliper bleed ports for better bleed integrity.
Reach adjustment dial for tool less reach adjustment.
