Dominion A4 Brake Kit

The Dominion master cylinder is factory-tuned for the shortest dead travel and a precise bite point. The Dominion A4 brake caliper utilizes four pistons in the structurally most stable design. It features a cold-forged caliper and a KingPin mounting screw for the structural support of the pads, which increases stiffness.

With a motorsport-inspired two-stroke dual-port bleeder system, industry-leading DOT 5.1 fluid, and a Kevlar hose, the hydraulic system is designed for ultimate performance at all temperatures and easy maintenance.

The Dominion A4 offers the proprietary QuickBite² system for fast and consistent bedding in, combined with our D-Series rotor to manage heat with less brake noise.

Available in SFL (Small Finger Lever) - ergonomically designed for smaller hands.

Rotors and mounts are not included.
