FOR A BETTER, BEST BRAKE: DOMINION T SERIES

DOMINION T SERIES OVERVIEW

While speed might be the most alluring part of performance, it is absolute control that allows your limits to be pushed further. Creating confidence through amazing and, above all, reliable performance sets the Dominion brakes apart as one of the most influential components of a better, best ride. Doing so in an even lighter construction while not compromising reliability or performance in the least makes for an unbeatable braking solution.

“The market’s absolute finest in terms of performance and reliability made with the world’s finest materials. “

Redefining performance componentry by defining performance is the tactic by which the Hayes Dominion brakes were developed. Instead of simply adding more raw power to the existing brakes, merely adding power to conventional design, Hayes chose to identify what factors contribute to an overall better performance. While power was one component, it is how that power is used which provided the most insight. The search for the perfect relationship between absolute power and control ensued and the creation of a new standard for braking performance was set in motion. The fruit of perhaps the most comprehensive mtb brake testing regimes in history, incorporating expertise from Hayes' braking engineers from other sectors, the definitive mtb brake was created. After the launch of the A series, the only way to make the Dominion more performance oriented involved making the component lighter through more sophisticated materials...carbon fiber levers, titanium internals and a tooled adjustment knob in lieu of an external adjustment solution.

DOMINION T SERIES In The News

These are the easest 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”

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

Bike Mag

If you’re chaing the harnd and arm fatigue gremlines but havenet esperimented with more pwoerful easier to use brakes, consider this and endorsement from a week-anded man who’s now less sore at the bottom of every decent.”

Bikeradar

The Dominions offer more than enough stopping performance, combined with excellent modulation. I’ve also found the Dominions to be reliable longer-term, experiencing no issues”

Enduro-mtb

In our 2024 MTB brake comparison test, Hayes made it from an insider tip to test winner! The Dominion T4 deliver a tremendous performance, both on the trail with their pleasant brake feel, and in the lab with excellent data”

Enduro-mtb

If the impressive power and lever feel wasn’t enough, the Hayes Dominion T4 comes out on top of the competition with the lowest weight, along with useful technical features like the Crosshair Alignment system”

PINKBIKE

What has impressed me again and again about the Dominion T2s was just how consistent they’ve been across long runs and extended periods of use”

Bikeperfect

Hayes Dominion T4’s are some of the best brakes I have used, the sensitive, light action levers flattering braking ability allows you to apply ample amounts of power perfectly. Not only does the light pull of the lever help braking accuracy it can also contribute to reducing arm pump on long rough descents so you can keep riding hard”

Bikeperfect

A force to be reckoned with and it has cemented its spot among our favorite brakes”

The T Series Dominion brakes by Hayes take the universally lauded A Series base build and complete it with carbon-fiber levers, titanium hardware, composite reservoir covers, pads with aluminum backing plates, and precision machining of excess material...to ensure minimum weight with maximum performance guaranteed.

Carbon Fiber Levers

The T Series boasts carbon fiber levers molded into the exact same tried, tested and apporved geometry as found on the aluminum version. This lightweight material coupled with a tooled adjustment system represents a significant weight savings.

UN HEAVY METAL - Titanium hardware + Aluminum backing plates

In an effort to optimize weight even further, all internals and hardware that could be made from titanium were subsititued for this prestigious material. Less grams, same performance. Likewise, the backing plates for T Series brake pads are made from aluminum to ensure a lighter weight solution.

POWER, Perfected

Immediate engagement is conferred via the individually calibrated master cylinder reservoir cutoff as fluid is pressurized instantly. The STABLE RATE LINKAGE geometry of the brake lever allows for one of the lowest force applied to power applied ratios in the industry. More Power, less effort. To ensure that braking force never degrades despite even the strongest force applied to the lever Kevlar reinforced hose resists expansion and increases overall power and efficiency The KingPin design is a structural pad retention bolt that reinforces the caliper, and thus increases power, while keeping the pads in place.

PERFORMANCE: Fight the Trail, not your brakes

Dominion level performance derives from not only raw stopping power but through creating a system that inspires greater confidence and an overall better experience in the saddle . Most solutions from other brands use bushings to facilitate the movement of the lever, the Hayes Dominion uses sealed bearings to require as little force as possible to actuate the brake, offering best-in-class, low friction tactile feedback to the user. The piston glide ring, a technology first used in suspension forks, contributes to even smoother actuation.

CUSTOM PERFORMANCE: One Brake, Adaptable to Your Needs

“Power, modulation, feedback and lever feel all improve the rider experience and inspire confidence, but the brake must also conform to riders’ physical needs and wants to feel like a perfect extension of the athlete. By incorporating a patented tool-free reach adjustment the engineers at Hayes were able to deliver one single solution that can easily be adapted to every rider’s needs. Although the Dominion is tuned at the factory for immediate pad engagement, through the use of a tool the system can be adjusted to add the desired amount of dead stroke (how much action is required on the lever to engage pads toward the rotors) “

CONSISTENT, RELIABLE, DEPENDABLE: UNWAVERING PURE PERFORMANCE

The best performance in the world is great but ultimately not worth much if you can’t guarantee consistency of that performance. An athlete needs no surprises and above all other components, his or her brakes need to represent a constant, dependable performance. Hayes didn’t develop the Dominions to hit an amazing performance metric every now and again, but rather put as a priority the reliability of the performance first and then began to increase absolute performance once its calling card reliability could be guaranteed. The Dominion incorporates an aluminum piston, as aluminum offers a great deal of consistency and functions smoothly across operating temperatures. DOT 5.1: the decision to use DOT 5.1 was made to ensure consistency as it is viscosity-stable across operating temperature range in addition to having the highest wet boiling point of all bicycle brake fluid options available on the market. DOT 5.1 is also perhaps the most regulated brake fluid on the planet, found on every corner of the globe and is consistent from region to region and brand to brand. In other words, no matter where in the world you find yourself, no matter what brand of fluid you find, your performance is guaranteed as no variables are present amongst DOT 5.1 offerings. Nothing says reliability like a Lifetime Leakproof Warranty and Hayes are proud to offer one as a testament to their confidence in such a well-engineered product.

CROSS OVER TECH

The double bleed port, Two Stroke, on the caliper allows for caliper only bleeding and is paramount in guaranteeing a highly functional system, free from any impurities or air. This bleed over (no pun intended) from the powersports sector highlights the competitive advantage that having a large-scale research and development department that operates on diverse applications.

Crosshair Caliper Alignment

An outwardly simple bit of tech that represents an amazing utility for the user. The Crosshair Caliper Alignment system allows for perfect milllimetric adjustment of the calipers, ensuring precise and perfect alignment with zero guess work. It facilitates not only initial set up but also guarantees perfect alignment is maintained even when removing and reapplying calipers during maintenance.
