"not the way to do it" ?
After doing it for 25 years I beg to differ
It's a viscous circle, the less the bleed nipple is used the more chance of it seizing when you do eventually need to use it.
I've had plenty of calipers apart and there's always some moisture and dirt in the corner, I'd prefer to get rid of it rather than chance it going back up the line.
Whatever you're happy with
