Cataloguing
There are different systems for the cataloguing of brake pads. The most frequently used system in Europe is the WVA numbering system.
The cataloguing system used in North America, and recognized around the world, is the standardized part numbering system for brakes and clutch facings issued by the Friction Materials Standards Institute (FMSI). FMSI's mission is to, "Maintain and enhance this standardized part numbering system for all on highway vehicles in use in North America." http://fmsi.org/home/]
