Tighten razvaltsovanny nuts (3) to the specified value of the moment of an inhaling. Moment of an inhaling (a): 16 N • m (1.6 kg-m, 11.5 pounds feet).

  • For air drain only from the main cylinder, it needs to be removed from the car.
  • The procedure of removal and installation of the main cylinder and drain of air is described in the Section the Main cylinder of coupling.
  • Avoid hit of liquid on the painted surfaces.
  • You watch that the tube (1) and a hose (2) did not concern the car or other parts.
  • Reliably establish all clips.
  • Reliably establish an E-shaped ring (3).
