Checking brake and clutch fluid level Fluid level should never fall below the MIN mark on each reservoir (fig. 35). If level drops below the limit, air might get into the circuit and affect the operation of the system involved. Brake and clutch fluid must be topped up and changed at the intervals specified in the routine maintenance chart (see Warranty Card) by a Ducati Dealer or authorized workshop. 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 an authorized workshop to have the system inspected and any air drained out of the circuit. Warning Brake and clutch fluid will damage paintwork and plastic parts if accidentally spilled. Hydraulic oil is corrosive; it may cause damages and lead to severe injuries. Never mix different quality oils. Check seals for proper sealing. E Important It is recommended all brake and clutch tubes be changed every four years. 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 is air in the circuit. Contact your Ducati Dealer or an authorized workshop to have the system inspected and air drained out. Warning Brake fluid level will increase as clutch plate friction material wears down. Do not exceed specified level (3 mm above minimum level). MAX MIN fig. 35 46
