SERVICE MANUAL TORQUE CHARTS BRAKE GROUP MOUNTING BOLT-NUT Tighten brake group mounting bolts to the torque  values listed   from  the  nut  side. Since some mounting holes in   the   steering   knuckles   are   of   conical   design,   the knuckle    bolts    must    utilize    conical    mounting    nuts    to coincide   with   mounting   holes   in   the   knuckle.   These conical nuts have a smooth cone surface and the torque values are considerably higher than the torque values for regular nuts or prevailing type lock nuts.
