Checking The Brake And Clutch Fluid Levels - Ducati MONSTER S4Rs Anleitung- Und Instandhaltungsheft

Checking the brake and clutch fluid levels (fig. 44)
The levels must not fall below the MIN marks on the
respective reservoirs.
If the level is too low it can allow air to get into the circuit,
thus impairing the efficiency of the relative system.
Brake and clutch fluid must be topped up and changed at
the intervals specified in the routine maintenance schedule
E
(see Warranty Card) by a Ducati Dealer or Authorized
Workshop
Important
It is recommended that all brake and clutch hoses be
renewed every four years.
Brake system
If there is excessive play at the brake lever or pedal even
though the brake pads are still in good condition, contact a
Ducati Dealer or Authorized Workshop to have the system
inspected and any air expelled from the circuit.
Warning
Brake and clutch fluid is harmful to paintwork and
plastic parts, so do not allow it to come into contact with
them.
Hydraulic oil is corrosive and can cause damage and injuries.
Never mix different quality oils.
Check that the seals are in good condition.
48
Clutch system
If there is too much play at the control lever and the
motorcycle jumps or stops when a gear is engaged, this
indicates air in the system. Contact a Ducati Dealer or
Authorized Workshop to have the system inspected and
the air bled from the system.
Warning
The level of clutch fluid tends to increase in the
reservoir as the friction material on the clutch plates wears
out. Do not exceed the specified level (3 mm above the
minimum level).
