Martini® SD-400 is a premium DOT 4 brake and clutch fluid designed for modern and older vehicles requiring high-performance hydraulic fluid. It delivers strong thermal stability with a dry boiling point of 270°C and a wet boiling point of 163°C, ensuring consistent braking under demanding conditions.

Its advanced glycol-ether and borate-ester formulation provides excellent corrosion protection for steel, aluminium and alloy components, maintains reliable low-temperature flow, and resists oxidation and moisture absorption. SD-400 meets and exceeds the following specifications:

• DOT 4
• U.S. FMVSS No.116
• SAE J1704
• ISO 4925 (Class 3 & 4)
