Air Brake Antilock problems of the 2000 Jeep Grand Cherokee

I have a 2000 Jeep Grand Cherokee laredo that has problems with the front brakes since I bought it. The vehicle has 30,725 miles on it and I have had the brakes replaced 3 times. At around 12,000 miles, the car began to vibrate, shake and pull to the left whenever I decelerated. I brought it back to the dealer and they resurfaced the brake rotors. At 30,000 miles the same things began to ocurr, except that the pulling effect was more pronounced, where I actualy had to turn the wheel to the right as I came to a stop. After reading complaints from fellow Jeep owners (model year 1999-2004) who have had the same or worse experience, I had aftermarket rotors put on my vehicle by a non-Jeep mechanic. I believe that the manufacturer is using oem rotors that are made out of inferior materials. In addition, I am reasonably sure that a class action suit has already been brought against Jeep by the mason law firm regarding this exact problem.
