The general description

Assemblage of a drum-type brake

For the vehicles equipped with additional system of restriction of movement НПБ (an inflatable pillow of safety):

  • Service of components of an inflatable pillow of safety (НПБ) and near to them or works with electroconducting should be carried out only by authorised dealer SUZUKI. Non-observance of security measures can lead to inadvertent operation of system or put system out of action. Any of these two conditions can lead to a serious trauma.
  • Works on maintenance service should be begun not earlier than in 90 seconds after the ignition switch is translated in position «LOCK/ЗАМОК» and the negative cable is disconnected from the battery. Otherwise the system can be activated reserve energy of the module of sensor controls and diagnostics.

All fastenings of brakes are the important elements of fastening and can affect work of the vital details and systems, and-or considerably to affect repair cost. It is necessary to replace them with details having the same number or equivalent if such replacement is necessary. Do not use for replacement of a detail of the worst quality or substitutes. It is necessary to observe the specified values of a twisting moment of an inhaling at assemblage to provide long service life of all details. It is not necessary to use welding as it can lead to extensive damages and metal easing.

Assemblage of a drum-type brake has the system of adjustment of a backlash of a boot so the backlash between a drum and boots is supported to constants in any conditions. A back brake - drum-type type. At it supporting function when the brake lever is pressed and when the lay brake is used on equal road.

At it also double auxiliary function when the lay brake is used on inclined road and loading is distributed in a vehicle in a longitudinal direction.

Replace all components included in ремкомплект at service of the given drum-type brake. Grease all parts as it is specified.

If you remove any hydraulic components or disconnect a brake highway, pit air from brake system. Values of a twisting moment of an inhaling are resulted for the dry not greased fastenings.
