Valtra (Valmet) 4000 Metta

Brake fluid capacity & service interval

Valtra (Valmet) 4000 Metta uses brake fluid with a capacity of 0,3 liter. Service intervals include checks every 250 hours and changes every 2000 hours or 24 months. The data covers 5 configurations.

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

Additional Notes

  • The Valtra (Valmet) 4000 Metta series covers five variants — the 4100, 4300, 4400, 4500, and 4600 — all produced from 1994-1996, and all share identical hydraulic brake system fluid specifications across the board.
  • Each variant in the 4000 Metta series carries a brake fluid capacity of 0.3 liter, which is a relatively small reservoir volume consistent with a dedicated hydraulic brake circuit rather than a shared or integrated hydraulic system.
  • The 0.3 liter figure represents a service fill capacity, meaning the amount of fluid held within the hydraulic brake system during normal operation, not an overhaul or full-system flush volume.
  • A fluid level check interval of every 250 hours applies to all five variants under normal use conditions, reflecting a routine inspection cadence typical of agricultural machinery operating on scheduled hour-based maintenance.
  • The change interval is specified at 2000 hours or 24 months, whichever comes first, under normal use conditions. The dual-trigger structure accounts for both high-hour working machines and lower-utilization units where calendar aging of the fluid becomes the limiting factor.
  • The 24-month calendar limit on brake fluid replacement is consistent with the hygroscopic nature of brake fluid, which absorbs moisture over time regardless of operational hours, gradually lowering its boiling point and reducing braking performance.
  • The uniformity of specifications across all five 4000 Metta variants — 4100 through 4600 — indicates no differentiation in brake system design or fluid capacity between the lower and higher models within the 1994-1996 production range.
