CHECKS AND MAINTENANCE

FRONT BRAKE LINING CONTROL

In order to verify the wear condition of front

brake is enough to view the plincer from

the bottom, where is possible to glimpse

the brake lining tails which will have to

show a brake of 2 mm in thickness. If the

stratum is lesser let’s start replacing them.

Note

Perform the check according to the times

shown in the table on page 58.

WARNING

Failure to promptly replace the brake pads

can result in a considerable reduction of

the braking action and in damage to the

brake disc.
