Steyr Multitrac/Kommunal 900

Brake fluid capacity & service interval

Steyr Multitrac/Kommunal 900 uses brake fluid with a capacity of 0,4 liter. Service intervals include checks every 250 hours and changes every 2000 hours or 24 months. The data covers 6 configurations.

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

Additional Notes

  • The Steyr Multitrac/Kommunal 900 series hydraulic brake system holds a uniform 0.4-liter fluid capacity across all six listed variants, including the M952, M963, M952a, M963a, M968, M968a, and M975a configurations along with their KM-designated Kommunal counterparts.
  • A 0.4-liter capacity is a relatively small reservoir volume, consistent with a dedicated hydraulic brake circuit rather than a shared or combined hydraulic system, where fluid volumes are typically much larger.
  • All listed variants share an identical check interval of every 250 hours under normal use conditions, indicating a routine inspection point rather than a fluid replacement event.
  • The change interval is set at 2000 hours or 24 months, whichever comes first, under normal use conditions. The dual-trigger structure means calendar time can mandate a fluid change even when the hourly threshold has not been reached.
  • A 24-month maximum service life for brake fluid reflects the hygroscopic nature of glycol-based brake fluids, which absorb moisture from the atmosphere over time and can lower the fluid's boiling point regardless of operating hours accumulated.
  • The specifications apply uniformly across the M952, M963, M968, and M975a model designations, as well as the "a" suffix variants, with no differentiation in capacity or interval between base and revised model iterations.
