Peter:

Now that is quite interesting. You are saying that a hose could, potentially, allow fluid to move up toward the master but restrict flow downward when the brakes are applied. If this is the case, then all of my conclusions might be premature. With the brake hoses being rather low cost, I think that I'll just replace the two front hoses and be done with it. Then deal with the suspension issues if the problem does not go away.

I did already confirm that the tire pressures are all identical, 32psi, on all four, so that is not the problem.

I had a similar problem on a W123 before I sold it. I rebuilt the front calipers completely and the problem remained exactly the same as before the rebuild. Talk about frustration.

Thanks for your advise and assistance.
