BRAKE FLUID DOT 5.1 is a brake fluid for hydraulic brake and clutch systems with a boiling point of at least 260 C and an extremely high wet boiling point of at least 180 C. Because of the low viscosity at low temperatures, particularly suitable for additional systems, such as ABS and ASR. - increases safety reserve against vapour lock - suitable for ABS, ASR, and ESP - ensures optimum brake performance and excellent response behaviour - increased wet boiling point
