Product details

Dominion A4 Brake Kit

Dominion's master cylinder is factory tuned for the shortest dead stroke possible and a crisp bite point. The Dominion A4 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 our D-Series rotor to manage heat with less braking noise.

Available in SFL (Small Finger Lever) - ergonomically tailored for the smaller hand.

Rotors and brackets not included.
