The award-winning Hayes Dominion A4 brakes are back – powerful 4-piston design as seen fitted on pro riders bikes.

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.
Sold individually, can be fitted LH or RH (comes with long 180cm hose to be cut down)
