Hayes Dominion A4 SFL hydraulic brake

The Dominion A4 hydraulic brake brings the shortest dead stroke of the lever, thanks to which the onset of braking force is quick and reliable. It is a four-piston brake that offers unrivaled stiffness thanks to a cold-forged caliper and King Pin Pad Retention bolt. The brakes are designed for ultimate performance under all conditions and with the easiest possible maintenance thanks to the DOT 5.1 brake fluid used.

Technologies:
  • QuickBite² system - for sensitive, gentle and quiet modulation of braking force. It dissipates heat and prevents excessive noise generated during braking. 
  • Crosshair Caliper Alignment System - significantly simplifies caliper adjustment
  • MRC (Modal Resonance Cancellation) - minimizes vibrations, reducing overall noise and increasing braking power
  • Low Input - High Fidelity (LoFi) - low resistance system with predictable braking force onset
  • SRL (Stable Rate Link) - the same operation of the lever regardless of its distance from the handlebars
Product features
Two-Stroke Dual-port - for perfect brake bleeding via two bleed valves on the brake caliper
King Pin Pad Retention - the locking screw of the plates increases the stiffness of the four-piston caliper
Sealed Cartridge Bearings Lever Pivot - brake lever mounted with bearings
Fast and reliable braking thanks to the short dead travel of the lever
