I have a 1999 Buick park avenue. The ABS light has been on for a week and then past night when I went to press on the brake the car started making a grinding sound. It did that for about two blocks then the car just stopped going forward. It will go in reverse and it will go in drive. I checked the trans fluid and its clean and normal. The car will go on drive but it won't go forward. It feels like and emergency brake is on.
