Chang'an Honor / Ounuo

Brake fluid capacity & service interval

Chang'an Honor / Ounuo requires brake fluid with a capacity of 0,45 to 0,52 liters. Service intervals include checking every 10000 km or 6 months and changing every 80000 km or 48 months. The data covers 2 configurations.

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

Additional Notes

  • The Chang'an Honor / Ounuo carries a brake fluid capacity range of 0.45 to 0.52 liter across both the 1.3 and 1.5 engine variants. A range rather than a fixed value reflects normal variation in how much fluid remains in the hydraulic brake system at the time of service.
  • Both the 1.3 (SC6449) and 1.5 (SC6449) configurations share identical capacity figures, check intervals, and change intervals under normal use conditions, indicating no differentiation in brake fluid specifications between the two engine displacements.
  • The check interval is set at 10,000 km or 6 months, whichever comes first under normal use. A 6-month time-based trigger alongside a distance-based one accounts for brake fluid's tendency to absorb moisture over time regardless of mileage accumulated.
  • The change interval under normal use is 80,000 km or 48 months. A 48-month ceiling on brake fluid life reflects the hygroscopic nature of DOT-class fluids, where water absorption lowers the boiling point of the fluid over time even when distance thresholds have not been reached.
