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:

Indeed!

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 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.
