  • Hayes Dominion A4 Disc Brake

    Giving enhanced control and stopping power to the rowdy riders of enduro, trail, downhill and E-MTB rides, this excellent disc brake from Hayes features an all new system. With its four-piston technology, this intuitive brake setup features an adjustment for the lever travel and the pistons of the caliper for a defined increase in braking force when the pad contacts the disc.

    Easy to Adjust Hydraulic Brakes

    With a 2-stroke dual port bleed system for safe and efficient venting and a ball-bearing brake lever with tool-free dead stroke adjustment, maintaining the brake for top performance is simple and quick to let you get on with keeping your steed in control as master what the mountain throws at you.
