You can also remove the front wheel and flip the bike over, then add penetrating oils under the wedge. We know the wedge is corroded into place, so putting penetrating oil at the top won't do anything to loosen the wedge until it can soak all the way down. I'd say turning the bike over and getting penetrating oil on the wedge is probably the first thing to try. Also there are better penetrating oils than PB Blaster. Kroil, for one. Or one part acetone, one part kerosene, one part automatic transmission fluid, and one part mineral spirits or turpentine - AKA "Ed's Red".
