First let me discredit a couple of incorrect assumptions:
>>>Rotors DO warp. They warp from HEAT.
>>>Drilled, slotted or otherwise ventilated rotors do NOT significantly reduce braking capacity or braking surface. Case in point is high performance and race cars. Rotors are drilled or slotted for a couple of reasons. First is dissipation of heat. Second is shedding water in wet conditions. You can believe that if the braking capacity was reduced by this technique, they would not be used in those applications. After all, some high performance cars come from the factory with drilled rotors. And, NO , that does not add more stress points. Drilling and slotting is followed by chamfering the sharp edges. They may also be radiused to further relieve stress.
>>Also not what a brake really is and how it works: A brake converts the kinetic energy of motion into heat energy.

Now, having said all of that, I think that the problem here is that the brakes were simply too small for the application from new. While they may have the capacity, they also will generate a lot of heat. Bigger brakes from a later model pickup would likely help the problem. It is not unusual for rotors to warp after being in service for a period of time. These days, with most brakes being metallic or ceramic, the rotors wear down as the pads wear out. You can only turn them down to the dimension stamped into the rotor or listed in the service manual. Most modern rotors simply do not have enough "meat" on them to do a lot of resurfacing.
Regarding the Chinese rotors, you can get good or bad from the "land of almost right" these days. I have been running Chinese rotors on my Explorer for 2-1/2 years now with no problems. I also had a couple of sets that were constant trouble. Luck of the draw. Get the better guarantee.
