Checking brake pads for wear (fig. 56 and fig. 57)
To facilitate inspection without removing the pads from
the calipers, brake pads have a wear mark. If the grooves
in the friction material are still visible, the pad is still in good
condition.
Important
Have the brake pads replaced at a Ducati Dealer or
Authorized Workshop.
