You might have a bad/loose hose somewhere, or the cnxn at the vac pump itself is loose? Or a hose clogged? Or maybe you have a failing brake booster, took me awhile to diagnose that but a new one restored all to its previous glory. I wouldn't think a torn diaphragm in the vac pump would do that, they tend to just tear and are then bad. Not sure how the brake booster is made, but there is a diaphragm in there too, I guess mine just tore or something.
