AEON Cobra

Brake fluid capacity & service interval

AEON Cobra uses brake fluid with a capacity range of min to max. Service intervals include 12 months, 3000 km/24 months/200 hours, and 24 months. The data covers 6 configurations.

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

Additional Notes

  • Brake fluid capacity across all AEON Cobra variants is expressed as a reservoir level range rather than a fixed volume, meaning the hydraulic brake system is filled to fall between the minimum and maximum marks on the reservoir rather than to a precise measured quantity.
  • The Cobra 320 (2007-2012) and Cobra 350 (2008-2012) share an identical brake fluid change interval of 12 months under normal use conditions, reflecting a time-based service schedule with no distance or hour-based alternative.
  • From 2013 onward, the Cobra 320 and Cobra 350 moved to a multi-criterion change interval of 3000 km, 24 months, or 200 hours under normal use, whichever comes first. This triple-threshold approach accounts for vehicles that may accumulate hours or distance at different rates.
  • The Cobra 400, introduced from 2013, carries the same 3000 km / 24-month / 200-hour brake fluid change interval as the updated Cobra 320 and Cobra 350, placing all three variants on a consistent service schedule within that generation.
  • The New Cobra 50 specifies a 24-month brake fluid change interval under normal use, which aligns with the time-based component of the 2013-onward Cobra 320 and Cobra 350 schedules but without the accompanying distance or hour thresholds.
  • The shift from a 12-month to a 24-month time-based interval between the pre-2013 and post-2013 Cobra 320 and Cobra 350 specifications represents a doubling of the maximum allowable service period, alongside the addition of distance and hour-based triggers.
  • Brake fluid is hygroscopic, meaning it absorbs moisture over time, which is why time-based change intervals exist independently of distance or usage hours. A 12-month interval, as seen on the 2007-2012 Cobra 320 and 2008-2012 Cobra 350, reflects a more conservative approach to moisture accumulation limits.
