High performance silicone-based brake and clutch fluid designed to lubricate and protect critical brake system componentry while providing reliable stopping power. Anti-vapor lock formulation maintains responsiveness and performance by fighting vaporization and viscosity loss. Advanced chemistry resists corrosion, oxidation and is compatible with SBR, EPDM and natural rubbers. Ideal for use in vehicles where incidental contact of brake fluid can damage finishes. Exceeds the requirements of US FMVSS 116 DOT 5 specification. Dry Boiling Point 572F (300C), Wet Boiling Point 429F (220C).
