how do i adjust parking brake Options

[rosenfe]

on my 73,i recently installed rebuilt rear calipers,set venting.now hand brake lever will not fully engage parking brake,it ratches too high,too much slack..im assumong previous calipers were stuck and gave very little motion to hand brake lever.i undid 2 adjusting nuts under neath at cable,but not sure how to adjust slack.do i need to undo cable from caliper,then adjust?what direction do i turn cable?

Less likely problem, but last time I assembled cables I had too much play and
eventually found that one cable, where it went through the trailing arm bracket,
the 'C' clip was not in the groove. Didn't look obviously different, but when the
cable was pulled it allowed the cable to move rather than caliper arm.

definitely a possibility
