Alright, The rear brakes have started to grind a little. So while i'm at them it seems like a good time to do the front upgrade. After the mechanics of this are done. Can I attach bleeder hoses and bags to the valves of the individual wheels and let gravity pull the old fluid out as I continually top off the master cylinder reservior? If so, can all 4 of the wheel valves be opened at the same time? The reason and logic behind that question is that with all valves open the old fluid might(?) be flushed quicker and more completely.
