Dominion A4 Brakes

Hayes Dominion A4

Making power is easy.  Making power with the right feel, that was Hayes' challenge.  Hayes 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 A4 caliper utilizes four pistons in the most structurally rigid design.  It features a cold-forged caliper and KingPin structural pad retention bolt.

With a motorsports inspired Two-Stroke dual port bleed system, industry leading DOT5.1 fluid and Kevlar hose, the hydraulic system is engineered for ultimate performance 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.
