My traction-controlled Honda gets less brake life out of the rears than the fronts, supposedly due to the traction control. With data points of exactly two rear brake jobs, rear brakes last 80K miles each, and fronts just over 90K. It's hard to make an argument that traction control kills modern brakes early from that data, so I won't.
I have hard data on the as-new measured rotor runout on all my disc rotors of my entire fleet of 3 vehicles, which you may handily dismiss as statistically insignificant; I also have had zero problems with "cheap brakes" and "warped rotors" since starting to manage runout as a controllable metric. I also have very long brake life, on the order of 80-110K per set of pads. Which you may also dismiss handily as statistically insignificant.
Your proclivity in killing engines is hard data; suggesting your killing brakes might be related is just a theory. Deming liked theories; but he knew their limits. But when the "cheap brake" and "warped rotor" complainers fail to answer my repeated question "what was your as-new rotor runout" and they have NO DATA and I have my small set of data and repeated success; I know what answer I'm going with.
