NIO ET5

Brake fluid capacity & service interval

NIO ET5 brake fluid capacity is 0,9 liter. Service intervals require a change every 36 months. Data covers 2 configurations.

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

TypeSpecifications
ET5 100 kWh (2022- )
  • Use: Normal
  • Capacity 0,9 liter
  • Change 36 months
ET5 75 kWh (2022- )
  • Use: Normal
  • Capacity 0,9 liter
  • Change 36 months

Additional Notes

  • Both the ET5 100 kWh and ET5 75 kWh share an identical brake fluid capacity of 0.9 liter, which is a typical service fill volume for a passenger car hydraulic brake system.
  • The 36-month change interval applies under normal use conditions for both configurations, meaning the fluid is scheduled for replacement on a time-based cycle rather than a mileage-based one.
  • A time-based interval for brake fluid reflects the hygroscopic nature of brake fluid, which absorbs moisture from the atmosphere over time and lowers its boiling point regardless of distance driven.
  • The NIO ET5 specifications cover both the 75 kWh and 100 kWh battery variants introduced from 2022, and neither variant deviates from the 0.9 liter capacity or the 36-month service interval.
