vac bleeders work ok when the system is working good
and u use them for just flushing the system with new fluid every few years
they can help with removing air but not always
the best system is a pressure bleed but u push fluid from nipple back up toward and out master cylinder but dont ask me where to buy the tool

i am pretty sure the hole where the rubber brake hose goes into the caliper should be lower than the bleed nipple so maybe thats yr problem because if the nipple is lower u will never get the last bit of air out
this is where the vise grip check will prove its air in the calipers in 5 minutes
so if u have not tried the vise grip test it will take 5 minutes and prove if it calipers or master cylinder or u can keep fking round and waste time guessing hehehehe
