OK, One more update. Had the van to a second mechanic. I got the same results. Unfortunately my van has the OBD-II computer and I was told I could not use a rebuilt or used ABS unit because it has to be programed with the main computer in the van. Apparently once they are linked to VIN # you can't swap them out. I pulled the fuse on the ABS to see if it would make any difference, to my surprise after braking a few times it started braking straight again. The front left still squeals when applying the brakes, but I'll see how it handles and hopefully not be rushed into replacing that thing anytime soon.
