Aston Martin DB9

Brake fluid capacity & service interval

Aston Martin DB9 brake fluid capacity ranges between min and max. Service intervals include 16000 km checks, 12 month changes, and 16000 km or 12 month changes. The data covers 6 configurations.

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

Additional Notes

  • Across all DB9 configurations from 2008-2016, the brake fluid fill level is specified as "between min and max" rather than a fixed volume. This is standard for hydraulic brake systems, where the reservoir level is maintained within a marked range rather than filled to a precise capacity.
  • The Aston Martin DB9 from 2008-2012 covered a combined hydraulic brake and clutch system under a single fluid specification. From 2012 onward, the note shifts to "hydraulic brake system" only, reflecting a separation in how the two systems are documented.
  • For the 2008-2012 configurations, the service schedule separates checking and changing into two distinct intervals. Fluid checks are specified at 16,000 km, while fluid changes are required every 12 months regardless of distance traveled.
  • The 2012-2016 DB9 and the 2015-2016 DB9 GT combine the check and change into a single interval of 16,000 km or 12 months, whichever comes first. This differs from the earlier format, where checking and changing carried separate standalone intervals.
  • The 12-month change interval present across all configurations reflects the hygroscopic nature of brake fluid, which absorbs moisture from the atmosphere over time. Moisture absorption lowers the fluid's boiling point, making time-based replacement relevant independent of mileage accumulation.
  • The DB9 GT, covering 2015-2016, shares identical brake fluid specifications with the standard DB9 of the same period. Both follow the 16,000 km or 12-month combined change interval with a reservoir level maintained between min and max marks.
