They just changed the lifters......
19/12/18/20 and 10 have to be in place.
If that crap is all there, and you have a new cable with the correct mounts/stops; I'd make sure the lifter roll-pin is in place for an 85 pull, not an 86 pull.
If you look around, you'll see how that lever should sit at rest with a cable on it or something is not correct.
If you bought it non-working, I can understand the PITA crap but if it worked before, it should work again.
Search around (even EBAY pics help) and see how there lever sits with just a hair of free play prior to separation. Or something is amiss.
Did you change all the plates with OEM plates?? Or are you the "I don't run no rear brake guy"
I forget...
Easy silly issue, I'm just not there............................................. .
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
