Hayes Dominion A4 Disc Brake (Front or Rear) - Stealth BlackThis item is in stock at the warehouse, and may take an additional 2 to 14 business days to process before shipping.
With an extremely light lever-action and immense stopping power, the Hayes Dominion A4 are a great choice for aggressive enduro and downhill riding.
The Dominion A4 master cylinder is factory tuned for the shortest dead stroke possible and a crisp bite point. The caliper utilizes four pistons in the most structurally rigid design possible. It features a cold-forged caliper and KingPin structural pad retention bolt that increases stiffness.
With a motorsports-inspired Two-Stroke dual port bleed system, industry-leading DOT 5.1 fluid and Kevlar hose, the hydraulic system is engineered for ultimate performance across all temperatures and easy maintenance. The Dominion A4 features the proprietary QuickBite² system for fast and consistent burnish, coupled with their D-Series rotor to manage the heat with less braking noise.
These brakes are the regular lever size. SFL (Small Finger Lever) models are available via special order. Please contact us if you need the SFL configuration.
