Additional Notes
- Across all four variants of the Porsche Cayman 981 (EU) — the base Cayman, Cayman S, Cayman GTS, and Cayman GT4 — the brake fluid service interval is set at 24 months under normal use conditions.
- The 24-month change interval is a time-based specification rather than a mileage-based one, meaning elapsed time alone triggers the service regardless of how much the vehicle has been driven.
- No discrete fluid capacity figure in liters or milliliters is listed for any variant. Instead, the fill level is defined as the range between the minimum and maximum marks on the reservoir, which is a level-based specification rather than a measured volume fill.
- The brake fluid specification applies to the hydraulic brake and clutch system as a combined circuit, meaning a single reservoir and fluid type serves both functions across all four variants.
- The Cayman GT4 carries a narrower model year range of 2015-2016 compared to the 2013-2016 span of the base Cayman, Cayman S, and Cayman GTS, yet shares an identical 24-month fluid change interval and the same level-based fill specification.
- The consistent 24-month interval across all variants, from the base Cayman to the performance-oriented GT4, reflects a uniform normal-use maintenance schedule for the hydraulic brake and clutch system within the 981 generation.
