Extreme high performance polyglycol brake fluid which far exceeds the standards of DOT 4. Each bottle is filled with Nitrogen, increasing shelf life and eliminating contamination while factory sealed. Extremely high dry boiling point of 594°F (312°C) helps prevent vapor lock and brake fade during hard use, with excellent recovery time.
Extreme thermal resistance and stability: The very high boiling point (312°C / 594°F), superior to conventional DOT 5.1 non silicone base / DOT 5 silicone base fluids (260°C / 500°F mini) and DOT 4 (230°C / 446°F mini) enables effective braking even under extreme conditions.
Efficient when rainy: The very high wet boiling point (205°C / 401°F), superior to conventional DOT 5.1 non-silicone base fluid (180°C / 356°F mini) and DOT 4 (155°C / 311°F), enables continued brake system efficiency even when rainy. Indeed, DOT 3, DOT 4 and DOT 5.1 brake fluids have the property to absorb humidity in the air, which reduces their boiling points and increases the risk of encountering "vapor lock" phenomena. The wet boiling point is measured by humidifying the product with about 3.5% of water.
