With the bleeder screw/hose inlet in the center of the barrel & the pistons in the ends even if the pistons were stuck (not likely with a new cyl) you'd still get fluid out of the bleeder screw (like when you gravity bleed) unless the bleeder screw is plugged (no fluid coming out) but there's no shoe movement either & neither of them is likely to have happened & both happening together is extremely unlikely. Now I see the chaos! Are you SURE the hose ain't plugged & that you ARE getting pressure AT the cyl?
