Subaru WRX, VA (EU)

Brake fluid capacity & service interval

Subaru WRX, VA (EU) uses brake fluid with a capacity range between min and max. Service intervals include changes at 15000 km/ 12 months and 30000 km/ 24 months. The data covers 4 configurations.

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

TypeSpecifications
WRX 2.0T (2014-2019)
  • Use: Normal
  • Between min and max.
  • Change 30000 km/ 24 months
WRX 2.0T (2014-2019)
  • Use: Severe
  • Between min and max.
  • Change 15000 km/ 12 months
WRX STI 2.5T (2014-2019)
  • Use: Normal
  • Between min and max.
  • Change 30000 km/ 24 months
WRX STI 2.5T (2014-2019)
  • Use: Severe
  • Between min and max.
  • Change 15000 km/ 12 months

Additional Notes

  • Both the WRX 2.0T and WRX STI 2.5T share the same brake fluid fill specification for the hydraulic brake system, with the reservoir level maintained between the minimum and maximum marks rather than a fixed volume quantity.
  • Under normal use conditions, the brake fluid change interval for the WRX 2.0T is set at 30,000 km or 24 months, whichever comes first.
  • Under severe use conditions, the WRX 2.0T brake fluid change interval is reduced to 15,000 km or 12 months, cutting both the distance and time thresholds exactly in half compared to the normal use schedule.
  • The Subaru WRX STI 2.5T follows the same interval structure as the 2.0T, with a 30,000 km or 24-month change interval under normal use conditions.
  • Severe use conditions on the WRX STI 2.5T also call for a 15,000 km or 12-month brake fluid change interval, matching the halved schedule applied to the 2.0T variant.
  • Across the 2014-2019 model years covered, neither engine variant specifies a discrete fluid capacity in liters or milliliters, which is consistent with brake fluid servicing practice where the reservoir is topped or fully flushed to marked levels rather than filled to a measured volume.
