[QUOTE="Gear, post: 1884884, member: 60511"] 99.9% of all ABS lights on are a result of a rusted tone wheel on the rotor. This is a problem on all medium duty trucks, not just UPS trucks. Ford, GMC, International, Hino, Dump trucks, wreckers, service trucks, its all Meritor brakes. Your rotor has small grooves cut around the inside surface, the wheel speed sensor picks up the grooves. Basically the groves rust and fall apart. So your 52 grove teeth, turns into 51 and so on. The sensor sees this, and kicks the code which turns the ABS light on. Your brakes and rotor will be fine, its just the rusting of the teeth. The repair is, replacing the rotors, but they will just rust out and happen again. Dont believe me? Mechanic saying thats not true? Take a flash light and look for yourself. Go the front inner side of your rear axle, look through the 1" hole and you will see the grooves. They will be either clean cuts or a rusted mess. [/QUOTE]
