BYD Yuan, S1

Brake fluid capacity & service interval

BYD Yuan and S1 models require brake fluid with a capacity range of 0,6 to 1 liter. Service intervals include checks at 5000 km or 3 months and 7500 km or 12 months, with fluid changes at 20000 km or 12 months and 40000 km or 24 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 BYD Yuan 1.5 and 1.5T variants from 2016-2019 share a capacity range of 0.8-1 liter for the hydraulic brake system, while the 2020-2022 EV and EV360 variants carry a fixed 0.6 liter capacity, reflecting a measurably smaller reservoir in the electric powertrain configurations.
  • The 0.8-1 liter range listed for the 2016-2019 combustion engine variants represents a service fill tolerance rather than a single fixed volume, meaning the acceptable fluid level falls anywhere within that window during a top-up or change procedure.
  • The Yuan 1.5 from 2016-2019 carries a check interval of 5000 km or 3 months under normal use conditions, which is notably more frequent than the 7500 km or 12-month check interval assigned to the 1.5T variant covering the same model years.
  • The Yuan 1.5 from 2016-2019 has a fluid change interval of 20000 km or 12 months under normal use, which is half the distance and half the time of the 40000 km or 24-month change interval specified for the 1.5T variant of the same period.
  • The Yuan EV and EV360 from 2020-2022 share identical brake fluid specifications, with a 0.6 liter capacity and a change interval of 40000 km or 24 months under normal use conditions, indicating no differentiation between the two electric variants in brake system servicing.
  • The 2020-2022 EV and EV360 specifications do not include a dedicated check interval entry, unlike the 2016-2019 combustion variants, both of which carry explicit check schedules separate from the change interval.
