Air Brake Abs Warning Light problems of the 2001 Dodge Dakota

I ben having a problem with a number of front suspension and especially front brake problems which began about four months after purchase of the vehicle. The dealership absolutely refuses to investigate my problems. I nearly lost control of my vehicle at high speed on two different occasions. If there had been heavy traffic it would have resulted in a crash. I am about o replace my third set of front brake pads as they are unevenly wearing on the rotors. I have vibration in the front end constantly, and at 30 mph and above heavy sound of "clunking. ".
