Hayes Dominion A4 SFL Brake Kit

Featuring an award-winning design, the Hayes Dominion A4 SFL Brake Kit combines a robust construction with performance-enhancing technologies to give you powerful and consistent braking operation on your mountain bike (MTB).

All set for fast and fun trail riding adventures, this MTB hydraulic disc brake features the brand’s Small Finger Lever (SFL) design for a secure and reliable braking feel. Its intuitive lever design makes it a perfect choice for riders with smaller hands or those who prefer a smaller lever for a solid pull as you weave your way from trail to trail. Engineered for precision, this version also comes equipped with a four-piston caliper for excellent control and consistency, whatever the terrain conditions. Another highlight is this model’s range of technologies that include tool-free reach adjustment. As a result, you’ll benefit from the simplicity of being able to fine-tune the distance between your handlebar and the brake lever to match your riding style, personal preferences as well as the terrain.

MTB Disc Brake with Four-Piston Caliper

Dominion’s master cylinder is factory tuned for the shortest dead stroke possible and a crisp bite point. The Dominion A4 caliper utilises four pistons in the most structurally rigid design possible. It features a cold-forged caliper and KingPin structural pad retention bolt that increases stiffness.

Dual Port Bleed System and DOT 5.1 Fluid 

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.

Dominion A4 also features the proprietary QuickBite² system for fast and consistent burnish, when coupled with the D-Series rotor (available separately) to manage the heat with less braking noise.

The Hayes Dominion A4 SFL Brake Kit is a perfect choice of upgrade for riders with smaller hands who want to enjoy reliable braking performance on the trails.
