Check

2

Check brake disks (1) at front and rear axle

 Cracks can occur due to high stress.

 Brake disks (1) do not need to be replaced, if the crack length is (2) max. 25 mm. With perforated brake disks or those provided with sunk holes (1) measure the crack length (2) including the bore diameter.

If the cracks are open or the score marks are deeper than 0,5 mm



Replace brake disks (1) subject to separate repair order.
