Replacement pads for the Hayes Dominion A4 four-piston caliper. Pick Sintered T100 for maximum bite in wet and dry, or Semi-Metallic T106 for quieter, smoother modulation.

Compatibility & fit

Fits the Hayes Dominion A4 caliper only – the A4's four-piston pad is a different shape to the A2's two-piston pad, so the two aren't interchangeable. Bed in over the first 20–30 stops before relying on full power. Pad retention bolt not included; wheel removal is needed to change pads on current Dominion A4 calipers.
