Additional Notes
- All three configurations covered by the specifications — the U 90 (408), U 110 (418), and U 140 (418) — share an identical brake fluid capacity of 0.8 liter for the hydraulic brake system.
- A capacity of 0.8 liter represents the total fluid volume held within the hydraulic brake system, which typically encompasses the master cylinder reservoir, brake lines, and wheel cylinders or calipers combined.
- The Unimog (MB) 408 and 418 series both carry the same 0.8-liter figure across their respective variants, indicating no capacity difference between the two platform designations for brake fluid service.
- The specified change interval of 12 months applies under normal use conditions across all three variants for the 1992-2000 model years, meaning annual replacement is the standard service cycle regardless of mileage or operating hours.
- A 12-month brake fluid change interval is notably frequent compared to many passenger vehicles, which reflects the hygroscopic nature of brake fluid — brake fluid absorbs moisture over time, lowering its boiling point and reducing braking performance.
- The U 110 and U 140 both fall under the 418 series designation, yet both carry the same 0.8-liter capacity and 12-month interval as the 408-based U 90, showing no divergence in brake fluid specifications between the two series.
