HAYES Dominion A2 disc brake | Single brake
Based on the tried and tested Dominion A4, Hayes has developed a two-piston variant that is at home on local trails and in cross country.
The brake caliper was adapted from the Dominion A4 and guarantees high braking power and perfect heat management. There is a setting for the free travel on the lever and the associated position of the master piston. The brake promises to be intuitive and to show a defined increase in braking force when the pads hit, which ensures a high degree of predictability and control. Hayes is also particularly proud of the new bleeding system: the brake caliper is equipped with two bleeding openings, which are intended to ensure optimal ventilation of the system.
The position of the brake caliper on the brake caliper mount can be perfectly adjusted using a 2 mm grub screw.
