Towcat, it's a fairly uncommon situation as far as regular driving goes, but under the just right conditions you can run a stock GM setup low on pressure - it takes me a few tries to make it happen, and it don't always happen either, but the problem does exist, and from what I've been told by some older GM engineers they were aware of it however it never got fixed cause of financial reasons - basically the logic behind the whole thing was that under normal driving you ain't never gonna floor the brakes and crank the wheel like a maniac at the same time, as tis likely you gonna flip the truck over, the only time a normal driver would take these actions would be a panic stop during low-speed maneuvering, in which case the brakes will stop the truck dead in its tracks before the spindles of the front wheels even hit the full lock position. Or something like that... Dunno about Fords, never drove a hydroboosted one so I have no experience with them, so I take your word for it.
