🔧 Key Technical Details
🟡 Caliper Types
Nissin Samurai brake kits come in various caliper configurations:
2-piston Calipers
-
Typically use 2 big bore pistons (~27 mm diameter) for braking force.
-
Common choice for smaller motorcycles or scooters where balanced braking and light weight are priorities.
4-piston Calipers
-
Equipped with 4 pistons (30 mm & 32 mm sizes) for stronger, more balanced brake clamping.

Better suited for higher-performance bikes or heavier machines needing more stopping power.
Calipers use Y93B brake pad material, which is claimed to maintain stable friction and sharp performance even at higher temperatures — useful in racing or spirited riding. samuraibrake.com
