Mercedes-Benz G-Class, W463B (EU)

Brake fluid capacity & service interval

Mercedes-Benz G-Class, W463B (EU) uses brake fluid with a capacity range of min to max. Service intervals require a change every 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

  • All four W463B configurations covered here — the G 350 d, G 400 d, G 500, and G 63 AMG — share an identical brake fluid service interval of 24 months under normal use conditions.
  • The Mercedes-Benz G-Class W463B (EU) brake fluid fill level is defined as between the minimum and maximum reservoir marks rather than by a fixed volume, which is standard practice for hydraulic brake systems where the fluid level is checked against a translucent reservoir rather than measured by quantity.
  • The 24-month change interval applies to the hydraulic brake system across all four variants regardless of engine displacement or output, spanning the diesel G 350 d and G 400 d as well as the petrol G 500 and G 63 AMG.
  • A "between min and max" fill specification means the reservoir is topped up or assessed by visual inspection of the fluid level relative to marked graduations, rather than drained and refilled to a precise measured capacity during routine service.
  • The normal use condition tied to the 24-month interval applies uniformly across the 2019-2024 model year range for all four chassis codes: 463.349, 463.350, 463.260, and 463.277.
