Expanding on our award-winning Dominion A4. Our newest brake, Dominion A2, targets Cross Country and Trail riders. Dominion A2 features a two-piston caliper. Dominion A2 includes all the performance
from the Dominion A4, utilizing a compact, two-piston caliper.
With the Short Finger Lever (SFL) option, the Dominion is the ideal brake option for any rider who likes one finger braking or has smaller hands. Hayes product development team set out to design a brake system specifically designed for a smaller
ergonomic profile. JUNIT Dominion maintains all the power and feel of our proven Dominion
A4, but accomplishes this using a specifically designed smaller and narrower brake lever.
The SFL Dominion can be used in conjunction with either our Dominion A2 two-piston caliper or
our Dominion A4 four-piston caliper.
With optional lever sizes and two caliper choices, Dominion from Hayes Disc Brake now
offers a brake that’s ideal for your application.
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 A2 features the proprietary QuickBite² system for fast and consistent burnish, coupled with our D-Series rotor to manage the heat with less braking noise.
MASTER CYLINDER: LoFi (Low input / High Fidelity) – Speaks to the overall system feel. Master cylinder dead stroke tech / cam profile / feel
Cartridge-bearings used in the brake lever
Aluminum piston operates smoothly across operating temperatures
Piston glide ring - technology pioneered in suspension forks
CALIPER:Two Stroke – Dual caliper bleed ports for maximum bleed integrity
KingPin – Structural caliper pad pin
Crosshair Caliper Alignment System – Dramatically simplifies caliper installment and alignment
Patented Crosshair caliper alignment screws
Allows mechanics and end users to quickly and accurately set brake caliper with no rubbing of the rotor on the pads
Eliminates guesswork and trial and error
Makes set up process quick and easy for ‘out of the box’ build
The FEA-optimized modal shapes of D-Series rotors is intentionally designed to oppose that of Semi-Met T106 and Sintered T100 pads; this cancels out noise and vibration translating into more consistent braking
1.95mm material thickness enhances heat dissipation
QuickBite² – Offers riders the shortest path to high performance
