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.

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"

"These are the easiest brakes I've ridden in terms of maintaining grip down steep, greasy, janky North Shore trails without the benefit of suspension. It's a bonus that they still work like new"

"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."

Loaded With Tech

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
Adjustable Reach - Adjust your lever reach with ease while on the trail thanks to an intuive adjustment knob design

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.

Great Brake Power better than Magura MT7

I switched from Magura MT7 to Dominion A4 and I’m really happy. I do street trials and Magura is so hard to bleed and the braking point inconsistent.
Dominion has it all: stronger barking power compared with Magura, SRAM and easy to bleed.

Buttery-smooth lever feel and very powerful

The A4s offer a rare combination of buttery-smooth lever feel and very powerful braking.

I used to think the A4s were the best brakes on the market, but the new Hope Tech 4 V4s beat it in terms of sheer power on tap. I still prefer the A4s' lever feel, though. It's also easier to find Hayes parts in the US compared to Hope, at least for now.

My only quibble with the A4s is that pad spacing is probably narrower than stated - I wasn't able to fit a 2mm Galfer disc without it rubbing a bit.

These brakes are still fantastic though, and I don't think anyone who has the money to spare will regret buying them.

Hope this helps.

Great brakes but be careful

I haven’t gotten a chance to test them out fully yet but the brakes seem awesome. However this might be just me but when I was going through the website it didn’t occur to me that “brake kit” meant it was only one lever one hose and one caliper, so I only bought one, will be ordering another however be aware so you don’t make the same mistake I did.

Ali Clarkson recommendation

After Ali Clarkson started to fit the Dominion A4 on all his new bike builds I decided to try them myself and they did not disappoint.
Powerful, great modulation, super light lever feel and those alignment screws!
Will definitely buy another set for the second bike.

I bought these brakes ...

... to replace the set on my new bike, which is something I don't normally do. I usually just ride the brakes that come stock on a bike. However, after riding a bike that had these brakes, I was sold. Though the stopping power is fantastic, the FEEL of these brakes, in my opinion, is the best on the market. It helps that the levers look like little stealth planes as well! It checks all the boxes. Hayes is back baby!
