after i replied i thought about my 2000 caravan master. gene is correct. if i'm not mistaken, the caravan is "cross braked". in that the right front and left rear circuits are connected and the left front and right rear are connected. the resivoir is a [kinda] divided detachable plastic piece in that using a single fill tube [also detachable] to fill the resivoir, the divider wall is not very tall, so when you lose fluid for whatever reason, it doesn't take much loss to lose all braking action because it is not a truely divided system. perhaps the abs accumulators are now considered the safety net ? i am considering using 2 small remote resivoirs to plumb a dakota style aluminium master to create a true "duel pot" master for my humpback.
