Subaru WRX, GR, GV (EU)

Brake fluid capacity & service interval

Subaru WRX, GR, GV (EU) models require brake fluid with a capacity range between min and max. Service intervals include changes at 15000 km/12 months or 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.

Additional Notes

  • The Subaru WRX, GR, GV (EU) brake fluid specification applies to the hydraulic brake system across both the Impreza 2.5T WRX and Impreza 2.5T WRX STI for the 2011-2014 model years.
  • Rather than a fixed volume fill, the brake fluid level is expressed as a range between the reservoir minimum and maximum marks, which is standard practice for hydraulic brake systems where fluid displacement varies with pad wear.
  • Under normal use conditions, the specified change interval for the hydraulic brake system is 30,000 km or 24 months, whichever comes first, for both the 2.5T WRX and 2.5T WRX STI.
  • Under severe use conditions, the change interval shortens to 15,000 km or 12 months for both variants, effectively halving the normal-use interval in both distance and time.
  • The WRX and WRX STI share identical brake fluid service intervals across both normal and severe use conditions, with no differentiation in the specifications between the two variants for the 2011-2014 period.
