Prestone DOT 4 Synthetic Brake Fluid, 12 fl oz DOT 4 Exceeds SAE requirements for Dry Boil Point for Extended Fluid Life and Added Margin of Safety High Temperature Synthetic DOT 4 Motor Vehicle Brake Fluid Complies with Federal Motor Vehicle Safety Standard 116 and SAE J1704. Minimum Wet Boiling Point 311º (155ºC). Formulated to provide outstanding performance in high temperature braking systems found in today's automobiles and trucks. Substantially reduces the possibility of fluid vaporization and eventual brake failure as a result of vapor lock, by providing high wet and dry boiling points. Provides protection against corrosion for metals within the braking system. Recommended for all ABS, Disc and Drum brake systems, as well as hydraulic clutches requiring DOT 3 and DOT 4 fluids. Safe to mix with any DOT 3 or DOT 4 brake fluid. Meets or exceeds DOT 3 and DOT 4 specifications. Packing - Recyclable Recommended for all ABS, disc and drum brake systems as well as hydraulic clutches requiring DOT 3 and DOT 4 fluids Provides corrosion protection for all metals within the braking system Compatible with all conventional brake fluids Substantially reduces the possibility of fluid vaporization and eventual brake failure Excellent performance in high-temperature braking systems
