What is dot 5.1 brake fluid?

DOT 5.1 brake fluid is a type of brake fluid used in the hydraulic brake systems of vehicles. It has a high boiling point, which makes it suitable for high-performance vehicles that generate a lot of heat in the braking system. DOT 5.1 brake fluid is compatible with both ABS and non-ABS systems and is designed to protect against corrosion and oxidation, which can damage the brake system. It has a distinct purple color and is made from synthetic materials that offer better stability and longer service life than traditional brake fluids. It should not be mixed with DOT 5 or DOT 4 brake fluids as they have different formulations and can cause brake system damage.
