ABS is nice, but if you "plant it" and all 4 tires lock up, the abs has no idea you are still moving.. The trick is at lease 1 tire has to be turning for the abs to kick in.. otherwise it would pulse at evert stoplight & stopsign, just to make sure you were stopped, and not sliding...
If you start to slide (and you will know it) let off the brakes (they arn't doing any good anyway) and let the truck straighten up, then reapply the brakes. the hardest thing to do is stop at a light, on a paved, ice covered, downhill, when it turns yellow on you and you don't have a choice.. Boy, that was fun... :rolleyes:
