Hayes Dominion A2 Disc Brake Pads

No, these pads are specifically engineered for the Hayes Dominion A2 hydraulic disc brake system. They will not fit other Hayes models, so please verify your brake caliper model before purchasing.

Choose organic pads if you prioritize quiet operation and initial bite, or sintered metallic if you need maximum stopping power and durability in wet, muddy conditions. Semi-metallic compounds offer a balanced middle ground, providing a blend of longevity and consistent performance across varied terrain.

You do not necessarily need to replace your rotors, but you should inspect them for deep scoring, thinning, or warping. If the rotor surface is smooth and within the manufacturer's thickness specifications, you can continue using it with your new pads.

Yes, proper bedding-in is essential for optimal performance. After installation, perform a series of controlled stops from moderate speed on a safe, flat surface to transfer a thin layer of pad material onto the rotor, which ensures consistent braking power and prevents noise.

These pads are sold as a replacement set for one caliper. While they include the friction material, please retain your existing pad retention pin and spring clip from your current setup, as they are typically not included in the replacement pad kit.
