Description

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 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.

Dominion In The News

"The Dominion brake is a winner in every sense.. If you are in search of a good brake, start with this one"

"I was pleasantly surprised by the Dominion A4 brake and I think most riders will be as well"

"I find myself recommending these to everyone that sees them on the trail."

"Overall, the Hayes Dominion’s performance was very impressive indeed, descent after descent we encountered nothing but consistent and precise braking."

"if you’re chasing the hand and arm fatigue gremlins but haven’t yet experimented with more powerful, easier to use brakes, consider this an endorsement from a weak-handed man who’s now less sore at the bottom of every descent."

Reduced Friction - A featherlight lever feel is acheived through a combination of an added glide ring on the piston and sealed ball bearings at the lever blade pivot
SRL - Our Stable Rate Link delivers a consistent lever ratio regardless of reach
Precise Engagement - Each Dominion is factory set to have the lowest dead stroke possible and a crisp bite point.
Built to last - Metal pistons are used to ensure that no matter the terrain or temperature your brake will continue to perform as it did on the first ride

Modal Resonance Cancellation (MRC)

FEA-optimized modal shapes of D-Series rotors are intentionally designed to oppose those of Semi-Met T106 and Sintered T100 pads, canceling out noise and vibration.


Crosshair Caliper Alignment screws allow for quick and accurate setup.

King Pin pad retention bolt adds strength.

2-Stroke dual port bleed system for maximum bleed integrity.
