FLUID BRAKE HEAVY DUTY 12OZ Specifications: Compositions: Diethylene Glycol Diethylene Glycol MonoButyl Ether Diisopropanolamine Hexaethylene Glycol Methyldiethanolamine Monosodium Salt Pentaethylene Glycol Phosphoric Acid Polyethylene Glycol Polyethylene Glycol MonoButyl Ether Polyethylene Glycol Monomethyl Ether Polypropylene Glycol Potassium Dihydrogen Phosphate Sodium Phosphate Tetraethylene Glycol Tetraethylene Glycol Monoethyl Ether Tetraethylene Glycol Propyl Ether Triethylene Glycol Triethylene Glycol MonoButyl Ether Triethylene Glycol Monoethyl Ether Triethylene Glycol Monomethyl Ether Prestone DOT 3 synthetic hi-temp brake fluid is designed to provide an extra margin of boiling point protection. The mix of polyglycol ethers ensures hot brake-system operation will not create dangerous vapor. This delivers braking power when needed by avoiding a spongy pedal. Both wet and dry boiling points exceed the minimum government standards. A comprehensive inhibitor package protects vital brake system metals.
