Additional Notes
- The NIO ET7 carries a brake fluid capacity of 0.75 liter across both the 100 kWh and 75 kWh variants, a figure consistent with a service fill rather than a full system overhaul, which would typically require draining and refilling the entire hydraulic circuit.
- Both variants specify a change interval of 36 months under normal use conditions, meaning the interval applies to standard driving environments rather than demanding or high-stress operating scenarios.
- The 100 kWh and 75 kWh battery configurations share identical brake fluid capacity and change interval values, indicating no differentiation in hydraulic brake system servicing requirements between the two powertrain variants.
- The note designating a hydraulic brake system is relevant because electric vehicles can employ brake-by-wire or fully regenerative braking setups that may not use a conventional hydraulic circuit, making the presence of a traditional fluid-based system a meaningful specification detail for the ET7.
