Front calipers not releasing

When at home without a “ pressure bleeder most of my life”. I have always started by a good slow thorough bench bleed on the Master then a slow gravity bleed after full assembly with drip hoses. I use a vacuum bleeder afterwards and then the good old slow push and taping with a mallet bleed to half pedal and Lock then release. The pressure bleeders can be real messy when not careful and ruin nice fresh paint.
