The Hayes Dominion A2 Hydraulic Disc Brakes expand on the award-winning Dominion A4 by taking the Dominion's crisp and quick actuating master cylinder and pairing it with a compact and lighter weight two piston brake caliper designed for XC and trail riders. The Crosshair Caliper Alignment and Two-Stroke Dual-port bleed system make it easier than ever to purge air from the system and align the caliper over the rotor for a rub free and powerful braking experience, while the proprietary QuickBite² system ensures a fast and consistent burnish to ensure a quicker pad bed-in time. Pair with the Hayes D-Series rotors to manage heat with less braking noise.
