Don't quite understand your logic in thinking the residual valve would be faulty and causing a problem. Also not sure that it is lower without measuring. There would have to be an air leak at the wheel cylinder as well as between the chambers in the booster for anything to siphon back. Even with a normal valve, would think the vacuum would draw under those conditions.
