Product details


HAYES Dominion A4 disc brake | Single brake

Braking power is everything. That was the challenge that the engineers at Hayes took on. The result is the completely newly developed Dominion A4.
The transmitter on the lever is adjusted at the factory to the shortest possible idle travel in order to generate a crisp pressure point immediately upon actuation. Four pistons are built into the cold forged, stiff brake caliper in order to be able to use the largest possible brake pads and thus to generate maximum braking force. In addition, the generous dimensions of the brake calliper have a positive effect on thermal management. The Crosshair Caliper Alignment System makes the assembly and alignment of your brake caliper much easier. The brake calliper can be adjusted quickly, precisely and without grinding with two set screws on the side.

The motorsport-inspired two-stroke dual-port ventilation system makes it easier to maintain your brakes and you always have optimal performance. The brake line is reinforced with Kevlar in order to withstand possible damage as best as possible and not to distribute the DOT 5.1 brake fluid on the trail.
