Brake system
If you note too much play on brake lever or pedal and
brake pads are still in good condition, contact your
Ducati Dealer or Authorized Service Center to have
the system inspected and any air drained out of the
circuit.
Warning
Brake and clutch fluid can damage paintwork
and plastic parts, so avoid contact. Hydraulic oil is
corrosive; it may cause damage and lead to severe
injuries. Never mix fluids of different qualities.
Check seals for proper sealing.
Clutch system
If the control lever has too much play and the
transmission snatches or jams as you try to engage a
gear, it means that there might be air in the circuit.
Contact your Ducati Dealer or Authorized Service
Center to have the system inspected and air drained
out.

Warning
Clutch fluid level will increase in reservoir as
clutch plate friction material wears down. Do not
exceed the specified level (0.12 in (3 mm) above the
minimum level).
