So Ive had more of a chance to address things. Replaced driver rear cylinder and shoes and the rear hose to the hard line. No change. Discovered that the rear parking brake had pulled the end of the cable off, and the head was bouncing about, but didnt seem to be causing any issue. Discovered that the front bearing had blown up when I went to address its noises. This seems to have been mostly the cause as I think the frame is slightly tweaked, creating undue strains on the bearing replaced about 3 years ago. I found bits an pieces through out the spindle as well as a large qunaity of magnetic material on the unused abs magnet. Put on a brand new bearing and seems like things are ok. I need to take it for more of a test drive, but want to do something about the brakes, as they seem just a touch soft.
