BYD M6

Brake fluid capacity & service interval

BYD M6 brake fluid capacity is 0,9-1 liter. Service intervals include checks at 5000 km or 3 months, and changes at 40000 km or 24 months, or 15 months. The data covers 4 configurations.

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

Additional Notes

  • The hydraulic brake system capacity for both the 2.0 (QCJ6480M) and 2.4 (QCJ6480MJ) engine variants of the BYD M6 is specified at 0.9-1 liter, indicating a relatively small reservoir volume consistent with a passenger van brake circuit rather than a full system overhaul fill.
  • Under normal use conditions, the check interval for the hydraulic brake system is set at 5,000 km or 3 months, whichever comes first, applying equally to both the 2.0 and 2.4 engine configurations across the 2010-2017 model range.
  • The normal-use change interval is 40,000 km or 24 months for both engine variants, meaning fluid replacement is tied to whichever threshold is reached first under standard operating conditions.
  • A separate first-change-only interval of 15 months is specified for both the 2.0 and 2.4 variants, which is shorter than the 24-month normal change cycle and reflects the practice of removing factory-fill fluid before a standard maintenance rhythm is established.
  • The 0.9-1 liter capacity range appearing identically across both engine variants suggests the M6 2.0 and 2.4 share the same brake system reservoir specification, with no differentiation in fluid volume between the two configurations.
  • The first-change-only interval of 15 months falls well within the 24-month normal change cycle, meaning the initial fluid replacement occurs roughly midway through what would otherwise be the first standard service period.
