HAYES disc brake Dominion A2 | single brake black / gray
Based on the tried and tested Dominion A4, Hayes has developed a two-piston version that is at home on local trails and in cross country.
The brake caliper has been 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 a high level of predictability and control. Hayes is also particularly proud of the new bleeding system: the brake caliper is equipped with two bleeding openings to ensure optimum bleeding of the system. The position of the brake calliper on the brake calliper mount can be perfectly adjusted using a 2 mm grub screw.
