I understand the physics of braking and the front does most of the work, hence front brakes are typically larger. But for my specific driving conditions on my FX and old Lexus, the rears would go first. Maybe it's because I live in the city and 90% of my drive time is in stop and go traffic or I'm riding the brakes. The rear brakes may be constantly engaged while someone who drives more on the highway and uses their brakes less doesn't have that problem. Or maybe it's my driving style coupled with the VDC which uses the brakes as well. On my BMW, the DSC system engages the brakes as a sort of E-diff instead of a real LSD. Haven't had to replace them yet, but I can see my rear brake pads are wearing more than the front (so that's 3 cars).
Who knows why. As I said earlier on my previous cars which were before the era of electronic traction control and ABS, the fronts always wore out first. Just not the case with my current cars.
