As part of routine maintenance work, the thickness of the driven disk must be checked every 20,000 km.
Make a control template from a steel sheet according to the sketch. Thickness 0.8 mm.

Raise the car.

The driven disk lining is normal if the template (4) can be inserted to the stop and the notches on the feeler gauge are not visible (see arrow).

If the cutouts are visible and the feeler gauge is inserted all the way, then the driven disk is worn out and must be replaced.
