Check of durability of fastening of wheel bolts


  1. After each installation of wheels it is necessary to check durability of fastening of bolts through some kilometers.
  2. The moment of an inhaling of bolts is offered by a key of 110 nanometers, i.e. not to "kill" them with in addition extended wheel key. Though this moment of an inhaling belongs to the faultless, slightly greased carving.
  3. Too strong or uneven tightening of bolts can lead to deformation of brake disks or drums. It leads to uneven braking and jolting when braking.
