BYD Seal

Brake fluid capacity & service interval

BYD Seal brake fluid capacity is 1,15 liters. Service intervals include a check every 20000 km or 12 months and a change every 40000 km or 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

  • The BYD Seal hydraulic brake system holds 1.15 liters of brake fluid across all listed variants, a capacity consistent with a full hydraulic circuit service fill rather than a top-up quantity.
  • All six variants share a brake fluid change interval of 40,000 km or 24 months under normal use conditions, whichever comes first.
  • The Seal 84 kWh and Seal AWD 84 kWh, both introduced in 2023, carry an additional intermediate check interval of 20,000 km or 12 months that is absent from the other variants.
  • The standard Seal and Seal AWD, both introduced in 2022, specify only a change interval with no intermediate check interval listed.
  • The Champion Edition and Champion Edition AWD, introduced in 2023, follow the same interval structure as the 2022 base variants, with a change at 40,000 km or 24 months and no intermediate check interval.
  • The 24-month time-based change interval reflects the hygroscopic nature of brake fluid, which absorbs moisture over time and lowers its boiling point regardless of distance driven.
  • The AWD variants share identical brake fluid capacity and change intervals with their respective RWD counterparts, indicating the addition of a front axle motor does not alter the hydraulic brake circuit volume in the specifications provided.
