HAYES disc brake Dominion A4 | set
Braking power is everything. That was the challenge that the engineers at Hayes faced. The completely new Dominion A4 was created.
The sensor on the lever is factory-set to the shortest possible free travel in order to generate a crisp pressure point immediately when pressed. Four pistons are installed in the cold-forged, rigid brake caliper in order to be able to use the largest possible brake pads and thus generate maximum braking force. The generous dimensions of the brake caliper also have a positive impact on heat management. The Crosshair Caliper Alignment System significantly simplifies the assembly and alignment of your brake caliper. With two grub screws on the side, the brake caliper can be adjusted quickly, precisely and without grinding.
The two-stroke dual-port bleeding system inspired by motorsport makes maintenance of your brakes easier and you always have optimal performance. The brake line is reinforced with Kevlar to best withstand possible damage and not to spread the DOT 5.1 brake fluid on the trail.
