Skidding and sliding??
When I gently apply brakes, it doesn't seem to want to slow down and when I apply more my Wagoneer slides and I lose control since it's all over the road! It's in 4WD, because the roads are snowy. Also, when backing out of driveway onto a downhill slope it skids downhill, no snow there! Are the brakes locking? What is the problem?
