Thanks for all the suggestions. As I stated earlier, it started with low fluid level with no apparent system leaks. I filled reservoir and have had very poor braking with ABS chattering. I got the bleeder screws on the front loose and functional. Yesterday I decided to do the same for the rear. I fought the rusted on rims for about 4 hours before getting them off. I used propane torch to heat and then cool with water, and then the same with atf/mineral spirit mix. The one side came off on the second heating cooling cycle. On the other side I did the same about 6 more cycles and also used BFH on inside and outside. I finally resorted to using a scissors jack between the leaf springs and the rim. I had twisted the jack on the first try with it. I repositioned it and used a 1/2" ratchet to crank it as tight as I could get it. I then heated the rim again and it did pop off. I was surely glad I thought to put a lug nut on as it jumped out with enough force to do bodily damage. I was not able to get rear bleeder screws loose with the amount of force I figured would not twist them off using a vise grips. The hex should have either been an 8 mm or a 5/16". Neither fit tight enough to keep from spinning on the bleeder. Evidently 22 years of corrosion made them smaller. 7 mm socket is too small. There again I heated and cooled numerous times. By then I had enough for the day and came in for the night. This morning I cleaned up the rear rims and hubs and reinstalled the rear tires after liberally using anti-seize on mating surfaces. I then preceded to bleed just the front brakes. Things seemed normal and I did it several times rotating from left to right. I put the wheels back on and took it for a road test. I actually had made things worse. Now the ABS light is on and does not function. ABS light was not on before. Also the brake warning light on the dash is lit which it was not before. Now the left front wheel locks up on slick surfaces. The overall braking effect is similar, but not necessarily straight. I will probably get new wheel cylinders and some brake line before I go after the rear bleeders to prevent time delays when I break things. Probably be next weekend before I get to it again. Time to start over. Not sure where to begin.

Today's Featured Article - History of the Nuffield Tractor - by Anthony West. The Nuffield tractor story started in early 1945. The British government still reeling from the effects of the war on the economy, approached the Nuffield organization to see if they would design and build an "ALL NEW" British built wheeled tractor, suitable for both British and world farming.
