Frequently Asked Questions

Which brake pads fit the Hayes Dominion A4 and T4?
Both the Dominion A4 and T4 use the same 4-piston brake pad shape. Any pad listed for “Hayes Dominion A4 / T4” is fully compatible with either model. They are not compatible with the 2-piston Dominion A2 or T2 calipers.
What compound should I choose: Enduro Pro, Factory Racing, or Standard?
🏆 Enduro Pro: Best for steep descents, heavy braking, eMTB, and wet weather 🏁 Factory Racing: Great all-rounder—quiet, powerful, and smooth in most conditions 🔧 Standard: Ideal for general trail use, commuting, and budget-conscious riders
Are sintered (metallic) or semi-metallic pads better?
It depends on your riding style: Metallic (sintered) pads last longer, resist fade, and perform best in wet and rough terrain. Semi-metallic pads are quieter and offer smoother modulation but wear faster. Many riders keep both: metallic for winter or DH, semi-metallic for trail days.
Do I need to bed in new Hayes Dominion pads?
Yes. Bedding in is crucial for quiet, powerful braking. To bed in your new pads: 1. Accelerate to ~20 km/h (15 mph) 2. Brake firmly down to walking pace (don’t stop fully) 3. Repeat ~20 times per brake This transfers pad material to the rotor and prevents squeal.
Why are my Hayes Dominion brakes noisy?
Common causes: • Metallic pads are naturally louder—switching to semi-metallic often helps • Poor bed-in or contamination can cause vibration and honking • Loose hardware or misaligned calipers can amplify noise • Try cleaning your rotors and re-bedding new pads properly
How long do Hayes Dominion brake pads last?
• Metallic pads can last several months of hard riding • Semi-metallic pads wear faster, especially in wet grit Replace when pad thickness is close to 1 mm or braking power drops noticeably.
Can I use aftermarket pads or do I need official Hayes pads?
Yes, aftermarket pads (like Gorilla Brakes) are fully compatible with Dominion A4/T4 calipers. Just make sure the shape matches Hayes D-Series pads and is listed as compatible with Dominion A4/T4. All Gorilla Brakes pads are engineered for a precise fit and rotor safety.
Do I need special rotors with Dominion brakes?
No, but Hayes recommends their D-Series rotors for optimal performance and minimal noise. Gorilla Brakes pads work great with standard 1.8–2.0 mm thick rotors from Shimano, SRAM, TRP, and more.
