Steyr CVT (Kommunal)

Brake fluid capacity & service interval

Steyr CVT (Kommunal) requires brake fluid with a capacity of 0,75 liter. Service intervals include checking every 250 hours and changing every 2000 hours or 24 months. The data covers 4 configurations.

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

Additional Notes

  • The Steyr CVT (Kommunal) brake fluid specifications cover the CVT 120, CVT 130, CVT 150, and CVT 170 variants, along with their respective KCVT counterparts, all sharing an identical hydraulic brake system capacity of 0.75 liter.
  • A 0.75 liter capacity is a relatively modest figure, consistent with the sealed reservoir volume of a hydraulic brake circuit rather than a large-volume overhaul fill.
  • All four model variants carry the same check interval of every 250 hours, meaning the brake fluid level and condition are due for inspection well before any full fluid change is required.
  • The change interval is specified as 2000 hours or 24 months, whichever comes first, applying under normal use conditions across all listed CVT and KCVT variants.
  • The dual-trigger change interval of 2000 hours or 24 months reflects the fact that brake fluid degrades through moisture absorption over time, making calendar age a relevant factor independent of machine operating hours.
  • The ratio between the check interval and the change interval is 8:1, meaning a brake fluid check is due eight times before a full fluid change is required under the 2000-hour threshold.
  • No variation in brake fluid capacity or service intervals exists across the CVT 120, CVT 130, CVT 150, and CVT 170 model lines, indicating a uniform hydraulic brake system architecture across the range starting from 2000.
