abs light on
it could probably be a lot of different things. i had to change all my lines, bleeder valves, rear brake cylinder and then bleed them all before it went off in mine. my dad's '89 had the same light on because of some sensor in the rear. the back would lock up if it were raining or you hit the brakes hard. i know that i need new pads and rotors and it's not on now so i'd say you can rule out that. any problems with your brakes? when you have to hit them hard, do the front or back lock up first?
