I'm not sure how to extrapolate that information to stopping distances..

I would have thought that as long as the driver & brake servo can
apply enough force it would make no difference at all to stopping
distances.

Thanks for that observation as I'm trying to derive as much real-world
benefit from the police cruiser report as is possible given Clare's astute
observations about EE and FF pads faring differently, but not because of
their coefficient of friction.

There are presumably 2nd order differences in pad performance, but we've no idea what they are. EE versus FF is not it seems the relevant criterion as long as the car can apply enough force to lock wheels with the pads. Whether all modern cars can do that with EE or not I also have no idea. FWIW certainly all historic ones can't.


I was hoping to get more insight from the scientific and mechanical folks
here.

you're getting a bit, but afaik none of us are brake specialists or researchers.
