Brake Abs Warning Light problems of the 1999 Cadillac Escalade

I own a 1999 Cadillac Escalade. It has 110,000 approximate miles. For the last few hundred miles, I've had trouble with stopping at a low rate of speed. Nearly running into my garage, and other vehicles in front of me. The abs light comes on intermittingly, then goes off. I've been told by friends/ relatives that there where previous complaints, and problems with the gm braking system. I've spoken with the sevice manager at david taylor Cadillac. On 03/24/2010. He said that there is not a recall on or for my vehicle.
