I bought front and rear drilled and slotted brake rotors. I installed these on my car using the same name brand of brake pads front and rear. The fronts were perfect. The rear rotors had defective black zinc coating that caked on my brake pads. This layer of coating prevented contact between the friction surface of the rotor and friction material of the pad. I only drove the car 1/2 mile. My rear brakes would not work properly. I sent Brake Performance 14 pictures and a series of emails describing this. They shrugged it off as cosmetic. I had the remaining defective coating machined off the friction surface of the rotors. I sanded and cleaned the layer of defective coating off my brake pads. After this cleaning, the brakes worked as expected. I have installed their products on 3 vehicles using 10 rotors and 2 drums. Only these last 2 rotors had defective coating. It's concerning that they never considered the safety implications of the defective coating. The front and rear rotors were stored together in the same environment prior to install.
