Hayes Dominion A4 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.

Technology :
  • 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
Specification :
  • Quiet and powerful
  • Adjustable lever distance without the need for tools
  • Fast and reliable braking thanks to the short dead stroke of the lever
  • Flip-Flop brake lever can be used for both right and left side 
  • King Pin Pad Retention - the locking screw of the plates increases the rigidity of the four-piston caliper
  • Two-Stroke Dual-port bleed system - for perfect bleeding of the brakes through 2 bleeding valves on the brake caliper
  • Sealed Cartridge Bearings Lever Pivot - brake lever fixed with bearings
  • Hoses reinforced with Kevlar for maximum resistance to expansion
  • Designed for use with Semi-Met T106 and Sintered T100 brake pads
  • Compatible disc: D-series 160/180/203 mm
  • Hose length: 1,000 mm
  • Weight: 310 g (100 cm hose)
