Additional Notes

  • The Mercedes-Benz 190 SL, W121-190SL covers the R121 body variant produced from 1955-1963, and the brake fluid specification applies to a combined hydraulic brake and clutch system, meaning a single fluid reservoir serves both functions simultaneously.
  • The specified fill level for the hydraulic brake and clutch system is defined as between the minimum and maximum marks, rather than a fixed volume, which is characteristic of a top-up or maintenance check rather than a full system overhaul fill.
  • Under normal use conditions, the inspection interval for the hydraulic brake and clutch fluid level is set at every 3,000 km, reflecting a relatively frequent check cycle consistent with mid-20th century service practices for hydraulic systems of this era.
