Hayes Dominion A4 Disc Brake Set

The Dominion A4 disc brake set by Hayes is the perfect package

The Hayes Dominion A4 disc brake set 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.
