Peugeot 308 III

Brake fluid capacity & service interval

Peugeot 308 III brake fluid capacity ranges between minimum and maximum values. The data covers 2 configurations.

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

TypeSpecifications
308 III HYBRID 180, DGX (2021- )
  • Use: Normal
  • Between min and max.
308 III HYBRID 225, DGY (2021- )
  • Use: Normal
  • Between min and max.

Additional Notes

  • Both the Peugeot 308 III HYBRID 180 (DGX) and HYBRID 225 (DGY) variants, introduced in 2021, specify brake fluid fill within the min and max reservoir markers rather than a fixed volume, which is standard practice for hydraulic brake system top-ups where displacing a precise quantity is less relevant than maintaining the correct operating level.
  • The min-to-max specification applies under normal use conditions for both hybrid configurations, covering the hydraulic brake system shared across each variant.
  • Because brake fluid absorbs moisture over time, a reservoir level sitting between min and max does not necessarily indicate fluid quality, only quantity, meaning interval-based replacement schedules are typically observed independently of the level reading.
