My 2003 3500 just started today with both the abs and brake light on, but recently a weird thing when i come to a slow stop,feels like something grabs before i come to a complete stop and while sitting there with foot still on brake something releases and truck nudges forward and it regrabs also feels like its holding me back for an instant after i take off. This happens some days and then doesnt some Could these be connected. New here not sure if ihijacked post. Cant find where to start new post, Help Please.
