l have a 2002 explorer sport. When l apply the brakes and come to a stop, it feels like the brake let go.The abs light is not on. It feels like the front right wheel lets go as if the abs is coming on. Does anyone know how to identify this problem? Someone told me it could be a reluctor wheel. I would like to know if someone knows how to identify this problem. I also wonder if it could be the rear brake sensor?
