ABS systems contain algorithms for application that are based on the OEM brake pad coefficient, any change in cF will result in a change to the ABS performance. Not sure why you think different, but that's how modern ABS works. It's possible that 20 years ago it didn't matter, but on today's vehicles it does.
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.
