Ligier Optimax
Brake fluid capacity & service interval
Ligier Optimax uses brake fluid with a capacity range of 0.5 to 1.0 liters. Service intervals are 30000 km/36 months and 50000 km/36 months. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Ligier Optimax 440 DCi and Optimax 505 both specify a fill level between the minimum and maximum reservoir marks for the hydraulic brake system, rather than a fixed volume, which is standard practice for brake fluid service fills where the reservoir level is the reference point rather than a measured capacity.
- The Optimax 505, introduced in 2008, carries a brake fluid change interval of 30,000 km or 36 months under normal use conditions, whichever comes first.
- The Optimax 440 DCi, introduced in 2009, specifies a longer distance-based change interval of 50,000 km, while sharing the same 36-month time-based interval as the Optimax 505.
- The 20,000 km difference in distance intervals between the two configurations means the Optimax 505 reaches its mileage-triggered service point considerably sooner than the 440 DCi, despite both variants carrying identical time-based intervals of 36 months.
