I noticed today in the snow my 01 didn't stop the way I know a car with abs should. Now ive had the truck for 5 months and never used the abs so what a day to find out! It sucks the truck slid right past my target! Now I looked into the truck unlike my dads 95 2500 theres no master pump with the four line's that im used to. Just a small black box and two perpotin valves? Is that it? I mean I found it odd no pulse back or noise of any kind. Oh ya no steering ether. Is this right or is something wrong and the light is a dummy. And it is the abs light that comes one at start not (rwal) so that should mean all 4 are abs. Right? Hope I can get more knowledge of this truck thanks.
