Check brakes for wear
Wear limit
Wear on the middle of the lining can be measured with a tape measure or a
ruler either at the shoulder bolt (long bolt near the disc run in) or at the play
bolt (short bolt near the disc run in). Here, the distance between the axle
flange and the edge of the housing of each bolt is measured (see illustration).
The amount of wear is determined to have been reached or exceeded by the
following criteria:
PAN 22-1
Long guide pin
> 98 mm
Short guide pin
> 73 mm
Brake Pad
Note!
Observe the wear limits of the brake pads.
Check the thickness of the brake pads for compliance with the legal

on the operation of the vehicle.
