1.8 mm wide at any point and no less than
2.5 mm between the brake lining and

Crash caused by brake failure
Worn brake discs and brake linings, as well as a
lack of hydraulic fluid in the brake cable, reduce
the braking power. This may cause a crash with
injuries.
 Check the brake disc, brake linings and
hydraulic brake system on a regular basis.
Contact your specialist dealer if any of these
components have become worn.
