When gravity bleeding do u do one wheel at a time or all four at once? I tried one ( right rear) and nothing happened. Doing a mad thrash trying to get the brakes on the coronet roadworthy so I can drive it out of here. They keep moving the fire evac lines closer and closer to town. Want to try to save one of my mopars at least ,if mother nature wants to have her way. Five towns here are no more. People are getting mighty nervous and air quality is horrible. If I can just get this thing limpable at least I can save one.My Barracuda will just have to burn.Neal Zimmerman, Eugene Oregon
