Compatible with HAYES Dominion A4, A4-SRL, and T4 4-piston calipers — engineered for ultra-quiet braking and refined lever feel rather than pad longevity.

Gorilla Brakes Factory Racing Organic Pads use an ultra-soft, non-metallic organic racing compound bonded to a silver back plate. This compound is designed to deliver instant bite, smooth modulation, and near-silent braking performance in dry riding conditions.

These pads are mechanically compatible with trail, enduro, downhill, and e-MTB braking systems. Due to the extremely soft racing compound, pad wear will be significantly faster than other Gorilla Brakes compounds, especially in wet, muddy, gritty, or abrasive conditions.

⚠ Important Usage Information

  • Optimised for dry weather riding
  • Extremely fast wear in wet, muddy, gritty, or winter conditions
  • No bedding-in process required — full braking performance immediately
  • Not designed for riders prioritising pad longevity or heat resistance
