Sorry should of said only just put that in but so far so good its certainly got the specification over the oem fluid "Motul RBF660 race brake fluid is suitable for all types of hydraulic actuated-brake and clutch systems requiring a high quality, dot4 non-silicone synthetic fluid. Specially designed to resist to high temperature of racing actuated-brake (steel or carbon) and clutch systems, this quality brake fluid is particularly suitable for the demands of racing and for those requiring a very high performance brake fluid. RBF660 also exceeds the DOT 5.1 and DOT 3 brake fluid standards, except for viscosity at - 40°C (-40°F). RBF 660 is a 100% synthetic brake fluid from polyglycol bases."
