IMPORTANT Brake disks (1) do not have to be replaced when the crack length (2) is a maximum of 25 mm. With perforated brake disks or those provided with sunk holes (1) measure the crack length (2) including the bore diameter. With gaping cracks and score marks deeper than 0.5 mm replace brake disks (1).		  
MEASURING Measure     
4 Measure thickness of brake disks on front and rear axles using caliper gauge (010) IMPORTANT Observe recommended limit dimensions so that the wear limit is not dropped below before the next brake pad change, if necessary replace brake disks (1): ↓
