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 calipers utilize four (Dominion A4) or two (Dominion A2) 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 & A2 feature the proprietary QuickBite2 system for fast and consistent burnish, coupled with the Hayes D-Series rotor to manage the heat, with less braking noise.

Both the Dominion A4 and A2 are available with Standard (BFL) or Small Form Levers (SML; designed for smaller hands).
