New brakes for '11 F350 PSD?

Yeah, so not true. But believe what you must, but don't state it as fact unless you repair or design ABS systems. I was actually talking about all the systems I have encountered have always worked the same way. The pump only activates when it "thinks" there is a locked up wheel or one slowing greater then the vehicle speed which again indicates tire lock up. In every case of premature ABS activation it has never once been the brake pads that caused it.

The only complication that's happen over the past 3 years (and again does not take into account the brakes coefficient factor is that now even under throttle or based on g load the car can apply one or more of the individual calipers to assist in traction/ride control. Still does not require you to reprogram the abs ecu every time you replace brake pads to ensure the have the correct coefficient.

Agree

'Thinks' is based on their look tables and is why when changing the
gear ratio (either directly with a new gear set, or changing tire
dia/rev's per mile)

The simple and very fast calculation is to look up the tire's rev's per
mile (MPH) vs the actual rev's per whatever time frame it is using
at that moment

Then it's algorithms (look up tables) will tell it whether the tire
is about to are skidding or not

The real complication is when the ABS system is also married to traction
control and the new anti-sway for towing (those highly integrated
systems)


The co-efficient of friction is part of the fray, but not directly
with the way I know it used to be and think still the case on how
they control.

Friction is not a consideration, directly, but it's outcome...in the
rev's per mile the tone ring (really just a gear) reports back via
the Hall Sensor
