The best just got better. The limited-edition Hayes Dominion T4 packs the power, sensitivity, and reliability the Dominion A4 is known for into its lightest chassis yet. Featuring a Reynolds designed and in-house produced carbon-fiber lever, titanium hardware, composite reservoir cover, pads with aluminum backing plates, and precise weight-reducing machining.

With an extremely light lever-action and immense stopping power, the Hayes Dominion T4 are a great choice for aggressive enduro and downhill riding.

The Dominion T4 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 T4 features the proprietary QuickBite system for fast and consistent burnish, coupled with their D-Series rotor to manage the heat with less braking noise.
