Dominion Disc Brake
Hayes brakes have fallen off of many rider's radars for some reason or another, however, we must remember that it was instrumental in bringing disc brake technology to mountain bikes over 20-years ago. The brand has plenty of experience in motorsports and the technology it brought to the table was truly game-changing. A lot has changed in 2 decades and in recent years, other brands have entered the fray and put Hayes on its back foot, but with the introduction of its new Dominion Disc Brake, it's slated to once again be a major player and has a brake that's packed with truly innovative features that's destined to put Hayes right back on the map.
There are plenty of brakes on the market with outright stopping power, but the key to providing confident braking is making sure plenty of modulation and feel is built-in so it isn't so much of a light switch, on, off experience. Starting at the tool-free reach adjustable lever, Hayes employs cartridge bearings at the pivots to reduce drag and provide stiff points of contact so you get a positive lever feel with zero slop. The Dominion’s master cylinder is designed with an extremely short dead stroke and with its revised cam profile when the pads contact the rotor, it comes with a crisp bite point. Joining the master cylinder to the rest of the system is a flex-free hose and high-performance DOT 5.1 brake fluid.
Moving down to the caliper, it features cold-forged construction and is engineered to be as rigid as possible and utilizes four pistons to move the pads, again contributing to that excellent power and modulation. Even the KingPin pad retention bolt is designed as a structural member to help increase stiffness. Also at the caliper are our two favorite "why hasn't anybody else thought of this" features of this brake. The first is its Two-Stroke dual port bleed system on either side of the caliper. With two bleed ports, it ensures better bleeds and improves the ability to evacuate air making sure spongy brakes are a thing of the past. The other feature is its Crosshair Caliper Alignment System which uses caliper alignment screws that allow for quick and easy alignment with no rotor rub or frustration.

Good Review from Pinkbike
"The Dominion brake is a winner in every sense, and it had to be if Hayes was going to get another chance at redemption. Throwing out convention and starting from scratch must have been a tough choice for a brake maker that has been in the game longer than anyone else, but it proved to be the right decision. If you are in search of a good brake, start with this one."
