98JGC

New owner of this 98 JGC, auto, 4.0 with 4 wheel disks ABS. I recently replaced front pads and rotors (bled). Brakes have operated great until we got some snow. The front wheels lock very easily and the rears pulse properly. I know this cause I had someone watch me in a parking lot. The vehicle slides very easily. I have not replaced the rear brakes yet and there is no ABS light. ABS light does work when you "key on"

I am Supposed to drive 150 miles in not so good of weather in a day or two. Is this because the front brakes are in much better shape ? Could I have done something to screw up the ABS while changing the pads ?

I pulled fuse 11 today to eliminate ABS its better but the fronts are still VERY grabby.

It is in 4WD.

Thanks in advance
