Brake Disc Pads problems of the 2015 Mazda CX-5

The front brakes on my car would not pass PA state inspection because of severe rust on the piston side of both front rotors. The outer surfaces of the rotors were fine. All of the pads were at 50% for wear. The vehicle is three years old, bought new, and has 38,000 miles of mixed driving. The dealer contacted the Mazda district manager and he refused to do anything about it and considered what I had as normal wear. I replaced the rotors and pads myself and was surprised at the improvement in stopping distance. Since this was happening over time, I was not aware of my loss in braking. After I replaced my brakes and personally called michael konzel, the Mazda district manager, he told me that this was considered normal and not a Mazda issue. I offered to send him pictures, but he said that he did not need them. The vehicle was stationary at the time, but driven daily.

I have a braking issue. When I brake my car at low speed, I rarely have any issue and my brake works well. But if I drive at a higher speed (>55mph) and brake relatively fast, I will feel like my foot is pushing on both brake and gas pedals, and my car will not slow down as it¿s supposed to. It feels like there is no significant force of friction between the brake pads and drums. The feeling of braking is not smooth either as if I was pushing the gas pedal at the same time. I almost hit the cars before me twice. This issue can be resolved with quick brake pedal relief and subsequent stepping on again. I may need to repeat this effort several times before it works normally. I believe there is some mechanical problem with it. I drive very carefully on high way now.
