more rear brake type 44 questions

[don & lori]

finally threw in the towel with my rear calipers.

they had gone beyond my patience and skill level.
got some rebuilts from Canadian tire.  left one went on fine.  when i
finished bleeding the right one, i titened the bleeder screw, but it just
kept
turning... uggh... stripped it and its leaking.  so i
stuck in the old bleeder screw from original caliper
and same thing,  when titened it leaked like crazy.
had another bleeder screw that came with the left
side, as i used the original in the new left side caliper.  so put in this
third bleeder screw and
it seems to work fine.

is this unusal?  should i be worried that it will leak,
or did i just damage the treads on first 2 i tried?

also note on the brake hose on right side looks a
little twisted as had to go extra quarter turn to keep
it tite.  shud this concern me?  wud it be better without that extra quarter
turn?

i am total newbie to fixing my brakes, so hope more experienced listers can
comment on above.
