How many turns on rear brake caliper piston?
 

Retracting rear pistons on 83 axle. Starting from
where the pistons sit when the caliper is rotated up away from disc I get maybe one turn clockwise where I can see the piston visibly moving into the caliper. Beyond that I can still turn the piston but retraction seems to stop. At this point the surface of the piston is maybe 1/16” poking out of the caliper. Should I be able to move the piston further in?

Fighting a dragging brakes after rear axle install…. Squeaky squeaky squeaky when off the brakes. Goes away when brakes applied. Handbrake is slacked off.
