DOT 4 Brake Fluid Boiling Point

Understanding the Boiling Point of DOT 4 Brake Fluid DOT 4 brake fluid is a brake fluid that complies with the standards established by the Society of Automotive Engineers (SAE) and the U.S. Department of Transportation (DOT). DOT 4 brake fluid typically has a boiling point of around 230°C (446°F) in its dry state and around 155°C (311°F) when wet. To meet DOT 4 standards, the fluid must meet these criteria: • The fluid must have a stable viscosity and be free-flowing at all operating temperatures. • DOT 4 brake … Read More
