The levels should not fall below the min marks on the respective reservoirs.
If the level is too low, air can get into the circuit, thus impairing the efficiency of the system.
Brake and clutch fluid must be topped up and changed at the intervals specified in the scheduled maintenance table reported in the warranty booklet; please contact a ducati dealer or authorised service centre.
Important
It is recommended all brake and clutch lines be changed every four years.

Brake system
If you find exceeding play on brake lever or pedal and brake pads are still in good condition, contact your ducati dealer or authorised service centre 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 fluid is corrosive and can cause damage and injuries. Never mix fluids of different qualities.
Check that the seals are in good condition.

Clutch system
If the control lever has exceeding 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 authorised service centre to have the system inspected and air drained out.
Warning
The clutch fluid level in the reservoir tends to rise as the friction material on the clutch plates wears out. Do not exceed the specified level (3 mm above the minimum level).
