Thanks for your help.
It is only the one rear pass. side caliper dragging. What's interesting is that this is the same dragging condition that happened once a few years ago. And at that time it was at the pass. rear caliper that was dragging. However, since then I recently replaced that caliper. Actually it was only about two months ago.
From other input I have received I have already purchased two new rear hoses and will install them in a few days. That way I can cut open the old rubber brake lines and see what the internal diameter really looks like.
Thanks again,
