Additional Notes
- The Unimog (MB) 425 carries a brake fluid capacity of 1 liter across all listed configurations, which is a typical figure for a hydraulic brake system reservoir fill rather than a full system overhaul volume.
- A 12-month change interval applies to the U 1300 (425) covering 1976-1984, reflecting the standard industry practice of annual brake fluid replacement to manage moisture absorption in glycol-based fluids.
- The U 1300, 1500 (425) spanning 1982-1992 shares the same 1-liter capacity and 12-month change interval as the earlier U 1300 configuration, despite the expanded model range that now includes the 1500 variant.
- Both rows specify normal use conditions, meaning the 12-month interval is not adjusted for severe operating environments such as heavy towing, frequent braking, or extreme temperatures.
