Hayes Dominion A4 Brake System

The Hayes Dominion A4 brakes are back and they're giving you even more ways to stop in your tracks!

So, here's the deal with these bad boys: they've got a seriously cool motorsports-inspired Two-Stroke dual port bleed system, top-of-the-line DOT 5.1 fluid, and Kevlar hoses. Basically, we've engineered these brakes to give you ultimate performance no matter the temperature, plus they're super easy to maintain.

But wait, there's more! The Dominion A4 comes with our exclusive QuickBite² system, which means you'll get fast and consistent burnish every time you hit the brakes. And to top it off, we've paired these babies with our D-Series rotor to keep things cool and quiet when you're slowing down.
