Hayes Rear brake Dominion A4 SFL

Creating a brake with power and the right feel was the challenge. Hayes has met it with a completely new system. The master cylinder of the Hayes Dominion A4 brake is factory-set for the shortest possible dead travel and a clean point contact. The Dominion A4 brake caliper uses four pistons in the most rigid design possible. It features a KingPin pad retaining screw for added rigidity. With a two-port bleed system, DOT 5.1 fluid and Kevlar hose, the hydraulic system is designed for optimum performance in all temperatures and easy, efficient maintenance. With new SFL levers for small hands.
