Hayes Dominion A4 4-piston brakes

Charged Advice 4-piston brakes provide the stopping power and modulation we love.  One of our favorite things about the Dominion A4 is that the levers are universal and can be swapped left or right making it a snap to setup your bike as MTB or Moto without swapping brake hoses. There are plenty of brakes on the market with outright stopping power, but the key to providing confident braking is making sure plenty of modulation and feel is built-in so it isn't so much of a light switch, on, off experience. Starting at the tool-free reach adjustable lever, Hayes employs cartridge bearings at the pivots to reduce drag and provide stiff points of contact so you get a positive lever feel with zero slop. The Dominion’s master cylinder is designed with an extremely short dead stroke and with its revised cam profile when the pads contact the rotor, it comes with a crisp bite point. Joining the master cylinder to the rest of the system is a flex-free hose and high-performance DOT 5.1 brake fluid.
