E39 (1997 - 2003)
The BMW 5-Series (E39 chassis) was introduced in the United States as a 1997 model year car and lasted until the 2004 when the E60 chassis was released. The United States saw several variations including the 525i, 528i, 530i and 540i. -- View the E39 Wiki

I couldn't find anything newer.

I never understood brake pad rebranding.Seems to me the friction code should prevent us from being confused by the extensive use of brake Marketing rebranding but even AMEC is in cohoots with the brake marketeers.

For example, this document says the following about rebranding tests:
- AMEC Manufacturers Guide
"If the material is produced for other companies ... this information is considered to be proprietary and will not be released"

I hope not. But, we'd have to see some more shoes to be sure.

EDIT: This textbook on brake friction coefficients implies the edge code should be printed on the shoes:
- Brake Friction Theory textbook (pdf)

Brake pads and shoes have markings on the edges that give the approximate coefficient of friction at low and high temperatures.

Notice that this textbook says that you want the SAME cold & hot coefficients, which would imply that EF is not as good as EE or FF.
