Martini® SD-400 Blue is a premium DOT 4 brake and clutch fluid formulated for vehicles where the manufacturer specifies blue-coloured hydraulic brake fluid. Its distinct blue colour assists with visual identification during servicing and fluid changes.

Engineered for high thermal stability, SD-400 Blue delivers a dry boiling point of 270°C and a wet boiling point of 155°C, ensuring reliable braking performance in demanding conditions. The advanced borate-ester and glycol-ether formulation provides strong corrosion protection for steel, aluminium and alloy components, maintains excellent low-temperature flow, and resists oxidation and moisture absorption.

Martini® SD-400 Blue meets and exceeds the following specifications:

• DOT 4
• U.S. FMVSS No.116
