For non burro burping in relation to brakes, stick the bleed cup on, add some fluid and squeeze the levers on and off repeatedly, can tap the hoses too and if it's struggling tie the levers closed for a while, it should burp air bubbles to the top.
Swapped shifter, no drama. Bleeding seems okay too.
But don't forget the burro burping to get out any bubbles after the swap
