Additional Notes
- The Porsche 928 (USA) brake fluid capacity of 0.2 liter applies to the hydraulic brake/clutch system, reflecting a combined circuit where a single reservoir serves both the braking and clutch actuation functions.
- The 928 covering model years 1986-1992 and the 928 GTS covering 1991-1995 share an identical 0.2 liter capacity figure, meaning the hydraulic system volume remained consistent across those two distinct variants despite differences in trim and production period.
- A 0.2 liter capacity is characteristic of a reservoir top-up or service fill quantity rather than a full system overhaul volume, indicating the figure represents the fluid held in the reservoir rather than the total volume circulating through all lines, calipers, and the master cylinder combined.
- Both configurations carry a normal use condition designation, which in brake fluid service contexts typically corresponds to standard road driving cycles as opposed to track or high-thermal-load operation that would otherwise shorten fluid change intervals.
