I know, logically it does not make sense. It could be faulty calipers, you know pistons in the caliper not engaging/releasing properly when braking at very low speeds. That is what I think is really happening, and it should be easy for a mechanic/mechanically inclined person to check. My dealer is certainly not interested in pursuing any avenues of investigation, so I will have to go elsewhere.
The Ford Escape had a TSB on something similar, but whether it applies here or not ...
