I'm hoping the shoes are good, wet or dry. At any rate I'm not planning on removing the drive unit to get to them. After more inspection I have found a small pilot hole inside the inching cylinder that takes the brake fluid back out to a hard line that tees off to each drive wheel (Once the inching cyl bottoms out). Bleeding the system looks like an adventure in itself. I see too many places for air to get trapped. Searching for parts for the inching cylinder now.

Thanks for your help.
