Additional Notes
- The Ducati S4 brake fluid level is maintained between the minimum and maximum marks on the reservoir, which is the standard method for a hydraulic brake system fill rather than a measured volume overhaul quantity.
- For the S4R S Testastretta Monster covering 2006-2009, the brake fluid change interval under normal use conditions is set at 36,000 km or 36 months, whichever comes first.
- The S4R Testastretta Monster covering 2007-2009 shares the same 36,000 km or 36-month change interval under normal use conditions as the S4R S Testastretta variant.
- A 36-month interval means brake fluid replacement is tied to a time-based limit regardless of mileage accumulation, which reflects the hygroscopic nature of brake fluid and how moisture absorption occurs over time even in low-use scenarios.
- Both configurations reference a hydraulic brake system, meaning the fluid capacity is not expressed as a fixed volume but is instead governed by the physical min-to-max range visible on the reservoir.
