parking brake equalizer is the assembly in the floor that looks like 2 cables attached to a single bracket which, in its turn, is attached to single cable attached to parking brake lever cable. adjusting nut is the nut on the single stud in the middle, between the 2 cables.
specs for lever is 5 to 9 clicks. kind of vast difference, but that's what they say.
