BYD L3

Brake fluid capacity & service interval

BYD L3 brake fluid capacity is 0,8-1 liter. Service intervals include checking every 5000 km or 3 months and changing every 20000 km or 12 months. The data covers 3 configurations.

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

Additional Notes

  • The BYD L3 hydraulic brake system holds between 0.8 and 1 liter of brake fluid across all three engine variants covered in the 2010-2015 model years, reflecting a range rather than a fixed fill volume.
  • A capacity expressed as a range, such as 0.8-1 liter, typically accounts for minor variation between individual systems, reservoir design tolerances, and fluid already present in brake lines and calipers at the time of service.
  • The 1.5-liter 79 kW variant with engine code QCJ7153A shares identical brake fluid capacity and service interval specifications with the higher-output 1.5-liter 80 kW variants carrying codes QCJ7153A5, A6, A7, BYD7153A, and BYD7153A1.
  • The 1.8-liter QCJ7183A4 variant also carries the same 0.8-1 liter capacity specification, indicating no meaningful difference in hydraulic brake system volume relative to the 1.5-liter configurations.
  • Under normal use conditions, a brake fluid check interval of every 5,000 km or 3 months applies to all three engine variants, whichever milestone is reached first.
  • The change interval under normal use conditions is set at 20,000 km or 12 months across all listed configurations, meaning a full fluid replacement is due roughly four times less frequently than a fluid level check.
  • The gap between the check interval (5,000 km / 3 months) and the change interval (20,000 km / 12 months) reflects standard brake fluid maintenance practice, where moisture absorption over time degrades the fluid's boiling point before visible contamination becomes apparent.
