Adaptive Cruise Control will reduce brake lining because it uses the camera, mathematically calculates your distance from the vehicle in front of you, and uses brakes to maintain distance at all times. So, for example, if the car slows down in front of your vehicle, brakes are applied either gently or slammed.
Brakes are applied by the rear first and added shortly after the fronts. Think of your bicycle, rear 1st in breaking. If you apply front first, you will flip your bike over.
Rotor warp is a bad term to use. There might be high spots on the face of the rotor, and needs to be honed down.
As for me, when I have to replace pads, I also replace rotors and maybe calipers too. Why? I want my pedial to travel just like if the car came from a factory,
Wow, that is so fascinating. I had no idea that radar cruise would pull the rear brakes first, before the fronts. I'm not doubting you, just curious how you know which brakes are applied first when using cruise, because I couldn't find any info on this elsewhere. It might be a factor for excessive rear pad wear.
I also heard the case with Volvos, where they pulled the brakes so hard when using adaptive cruise (either front or rear, or both, don't remember), that it would constantly destroy the rotors so the manufacture had to replace tons of rotors under warranty.
It's interesting that you mentioned bikes because when I ride my bicycle, I always pull both brakes at the same time, more biased to the front but modulating it obviously. If you are familiar with your bicycle, it is surprisingly hard to go over the bars for me personally. The only time when I pull more rear brake, is when I really need to slow down in corners, or while controlling speed in tight turns at slow speeds. But that's just how I ride, might be wrong, I don't know.
Thank you for the reply, I learned so much already just from joining yesterday!
