HAYES disc brake Dominion A2 | set
Based on the proven Dominion A4, Hayes has developed a two-piston variant that is at home on the 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 an adjustment for the free travel on the lever and the associated position of the master piston. The brake promises to be intuitive and to have a defined increase in braking force when the pads hit, which ensures high predictability and control. Hayes is also particularly proud of the new bleeding system: The brake caliper is equipped with two bleeding openings, which are to ensure optimal bleeding of the system.
The position of the brake caliper on the brake calliper mount can be perfectly adjusted using a 2 mm grub screw.
