Peugeot 404
Brake fluid capacity & service interval
Peugeot 404 uses brake fluid with a capacity of 0,65 liter. Service intervals include a check every 500 km and a change every 24000 km or 12 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 Peugeot 404 hydraulic brake system holds a capacity of 0.65 liter, a figure that reflects the total fluid volume the system reservoir and lines are designed to contain during normal service fill.
- Both the standard 404 (1961-1975) and the 404 Diesel (1966-1975) share the same 0.65 liter brake fluid capacity, indicating identical hydraulic brake system sizing across the petrol and diesel variants.
- A check interval of 500 km is specified for the standard 404 under normal use conditions, which represents a relatively short inspection cycle consistent with maintenance practices common to vehicles of that era.
- The 404 Diesel carries an additional specification not present in the standard variant: a fluid change interval of 24,000 km or 12 months under normal use, whichever comes first, combining a distance-based and a time-based threshold.
- The 12-month change interval on the 404 Diesel reflects the time-sensitive nature of brake fluid degradation, as brake fluid is hygroscopic and absorbs moisture over time regardless of mileage accumulated.
- The 404 Diesel shares the same 500 km check interval as the petrol 404, meaning both configurations require equally frequent fluid level inspections despite the diesel variant carrying the additional change interval specification.
