Hayes Dominion A4 Disc Brake

Item number: 71991

The Dominion A4 disc brake by Hayes - for the right amount of braking power


The Hayes Dominion A4 disc brake combines high braking power with a smooth lever feel and good modulation. The new dual port bleeding system is inspired by motorcycle racing and offers easy maintenance and improved brake functionality. Constant modulation over the entire lever travel ensure excellent lever control. The King Pin, which secures the specially developed pads, has an additional stiffening effect on the cold forged brake caliper. The hydraulic system is designed for easy maintenance and ultimate performance at any temperature. Minimised reach and a crisp contact point together with powerful braking - that's the Dominion A4.
