Brake fluid capacity & service interval

Maserati Quattroporte III, AM 330 uses brake fluid with a capacity of 0,5 liter. Service intervals require a change every 25000 km or 36 months. The data covers 2 configurations.

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

Additional Notes

  • The Maserati Quattroporte III, AM 330 brake fluid capacity of 0.5 liter applies to the hydraulic brake system, which is a relatively modest reservoir volume consistent with a sealed hydraulic circuit rather than a full system overhaul fill.
  • Both the 4200 and 4900 engine variants share an identical service interval of 25,000 km or 36 months under normal use conditions, meaning whichever threshold arrives first would trigger a fluid change.
  • The 36-month time limit on the brake fluid change interval reflects the hygroscopic nature of brake fluid, which absorbs moisture from the atmosphere over time and lowers its boiling point regardless of mileage accumulated.
  • The Quattroporte 4200 covers model years 1979-1983, while the 4900 variant spans 1979-1986, yet both share the same 0.5 liter capacity and the same 25,000 km/36-month change schedule across their respective production periods.
  • The normal use condition tied to the 25,000 km/36-month interval applies uniformly across both engine displacements, with no separate severe-use interval listed for either configuration.
