mac,that's not kosher how a bleeder works ,if that's one of the "New" parts -probably rebuilt- the WRONG bleeder screw might have been installed ,Can 'try' getting the 1/2 dozen "shaped" bleeder screws (w/same thread of course) from like NAPA and see if it opens an closes off like it should - otherwize bring the part back/ or replace it.This 'try' - better sometimes than redo-ing ALL that work completely over again
