In this case you probably just have larger reservoir, assuming the piston is the same sizes as your oem unit.\
JUST to be sure... your rear brakes are fed from the smaller reservoir, correct?
can't tell from your video but if you can hear a faint scrap scrap as you turn it your there. rears are harder to adjust as the rear end puts a lot of drag on the ability to spin.
BUT it looks good to me.
BTW the rears ( assuming you have the adjusters on correctly) will self adjust if you apply the brakes moving in reverse a few times.
