BRAKE DISCS

Dismantling-reassembly

Undo the brake disc attachment bolts and remove the disc. When refitting, eliminate any traces of rust to ensure that the disc is perfectly perpendicular to the hub.

Checking and measuring disc thickness

The minimum permissible brake disc thickness after wear is indicated in the table; if the measured value is less than the value in the table, the disc should be renewed. In the case of damage or deep scoring, the brake disc surfaces can be skimmed; after skimming, the brake disc thickness must not be less than the value stated in the table;

Brake disc thickness (values in mm)

Checking brake disc run-out

Also check that the run-out does not exceed 0.15 mm; this should be checked 2 mm from the disc's outer diameter.
