Well firstly, there is evidence that they can drag from time to time, so what
I'm interested in is a means to *be sure* there is no contact - rather then
hoping there isnt - a subtle but important engineering paradigm ;)
Especially since the 'standard' caliper arrangement seems a bit basic and
I have been wondering if there wasnt something better...

As you've probably seen on this mail list, GM went to some trouble with a
modified cylinder to cover this issue and I am looking into it.

I also have heard there are those on competitive economy runs that go
to considerable trouble over several aspects of fuel consumption management,
and do attend to this issue and as someone has commented on the wheel
bearings as well.

Granted, I am not in a competitive economy test, I just feel it prudent
to consider this if I am to embark on some form of economy test over a
3000km distance - where I am looking to manage 'some' of the issues which
could affect the outcome,
