WVA System5-digit European geometric standard
FMSI SystemNorth American D-number standard
Asian ReferencesOE / MK Kashiyama / Akebono
Database Size2,000+ cross-matched references
2. WVA Numbers (European Aftermarket Standard)
Created by the German Friction Materials Association, WVA numbers (e.g., WVA 23745, WVA 21647) define the exact physical dimensions, thickness, and caliper geometry of the pad regardless of vehicle brand.
3. FMSI D-Numbers (North American Standard)
The Friction Materials Standards Institute standard uses a 'D' prefix followed by a sequential number (e.g., D1080, D1377, D784) widely used by distributors across the United States, Canada, and Mexico.
4. Asian Aftermarket Cross-References (MK & Akebono)
Japanese and Asian aftermarket suppliers frequently reference MK Kashiyama (e.g., D2234) or Akebono (e.g., AN-650WK) catalog codes to identify shared brake pad shapes across Asian vehicle platforms.
