Additional Notes

  • The Mercedes-Benz EQB-Class X243 (EU) brake fluid specifications cover three variants introduced in 2022: the EQB 250+ (243.601), EQB 300 4MATIC (243.608), and EQB 350 4MATIC (243.612).
  • All three variants share an identical service interval of 24 months under normal use conditions, applied to the hydraulic brake system.
  • Rather than a fixed volume figure, the fill level for each variant is defined as the range between the minimum and maximum reservoir marks, which is a standard approach for brake fluid top-up servicing rather than a full system overhaul fill.
  • The absence of a discrete capacity value in milliliters or liters across all three variants reflects that brake fluid service on sealed hydraulic systems is typically governed by reservoir level rather than a measured quantity.
  • The 24-month change interval is consistent across the single-motor EQB 250+ and both all-wheel-drive 4MATIC variants, indicating no differentiation in brake fluid service scheduling based on drivetrain configuration.
