Additional Notes
- The JAC J6 / Heyue brake fluid capacity is expressed as a range of 0.64–0.69 liter across all listed configurations, which reflects the normal variation expected when filling a hydraulic brake system to the correct level between the minimum and maximum reservoir marks.
- The Heyue RS 1.8 (2013-2015) shares the same 0.64–0.69 liter hydraulic brake system capacity as the J6 variants, indicating no meaningful difference in brake circuit volume between the RS body style and the standard J6 lineup.
- The J6 1.5 VVT, J6 1.8 VVT, and J6 2.0 VVT all carry an identical 0.64–0.69 liter brake fluid capacity starting from 2013, meaning engine displacement has no bearing on the brake system fill volume in these configurations.
- All four listed configurations specify normal use conditions for the 0.64–0.69 liter brake fluid capacity, which in service terms refers to standard operating environments rather than severe-duty cycles such as frequent towing or repeated high-load braking.
- The capacity figure of 0.64–0.69 liter is consistent with a compact hydraulic brake reservoir fill rather than a full system overhaul volume, suggesting the specification applies to a standard service top-up or reservoir replacement procedure.
