Case - IH JXU Maxxima

Brake fluid capacity & service interval

Case IH JXU Maxxima uses brake fluid with a capacity range of 0,4 to 0,5 liters. Service intervals require a check every 10 hours. The data covers 8 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Case-IH JXU Maxxima series uses a hydraulic brake system across all listed configurations, meaning brake fluid serves both the braking function and the hydraulic actuation circuit rather than a conventional standalone brake reservoir.
  • The JX70U, JX80U, JX90U, and JX100U Maxxima models, covering the 2003-2008 production span, share a hydraulic brake system capacity of 0.5 liter.
  • The JX1070U, JX1080U, JX1090U, and JX1100U Maxxima models, introduced for 2005-2008, carry a slightly lower hydraulic brake system capacity of 0.4 liter, representing a 0.1-liter reduction compared to the earlier JXU variants.
  • All eight configurations across the JXU Maxxima range share an identical check interval of every 10 operating hours under normal use conditions, reflecting the demands of agricultural equipment that accumulates hours rapidly during field work.
  • A 10-hour check interval for brake fluid is notably short compared to typical automotive schedules, which is consistent with the high-stress, dusty, and vibration-intensive operating environments common to utility tractors.
  • The capacity figures of 0.4 and 0.5 liter represent service-level fill volumes for the hydraulic brake circuit, not full system overhaul capacities, indicating the amount of fluid held within the active brake circuit rather than a complete drain-and-refill quantity.
  • The 2003-2008 year range applies to the JX70U, JX80U, JX90U, and JX100U, while the four higher-numbered JX1000-series variants share the narrower 2005-2008 range, placing the latter group as later additions within the same overall model family.
