yes the adjustment for the tightness of the cables is under the center console, but the concern is that the cables themselves have got bound up and therefore won’t release properly. Odds are that the calipers themselves were the issue and you won’t have to worry about anything with the cables other than reattaching them to the new calipers and adjusting properly. Btw, I’ve got my old Haynes manual for the 4th gen maximas if you want it, I have no use for it.
