Air Brake Disc problems of the 2004 Nissan Titan

The front brakes on my 2004 Nissan Titan began shaking violently at 8100 miles in Jan '05. I took it to the dealer where they only resurfaced the rotors and put on new pads. Again in Apr '05 it started shaking causing me to almost lose control of the vehicle. I took it to the dealer and they informed me that they were aware of the problem, but they would have to order the new brakes from Nissan since the manufacturer was not allowing dealers to stock the parts. They had to order them by VIN. Nearly two weeks later my parts are not in and I am forced to put this unsafe vehicle on the road every day caryying my 22 month old twins. The dealer and Nissan don't seem to be concerned like it's no big deal. Does someone have to die before anything gets done with this?.
