Hayes Dominion T4 Disc Brake

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 QuickBite² system for fast and consistent burnish, coupled with their D-Series rotor to manage the heat with less braking noise.
