Motul produces and markets lubricants incorporating technologies tested and validated in the extreme conditions imposed by highly demanding engine manufacturers or industrial branches. Motul has risen above existing standards by developing products based on unconventional technologies like the Double Esters of the 300V range for cars and motorcycles or else the amine-free and boric acid-free technologies used in the aeronautics industry for machining titaniums.

Its strong involvement at the highest level of motorsport competition provides it with an unparalleled test bench for experimental formulas which are then rolled out as products for demanding clients.

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.  

High Performance brake bluid with very high dry boiling point of 617°F (325°C) and wet boiling point of 400°F (204°C). For all types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid. Specially designed to resist extreme high temperature generated by racing brakes (carbon and ceramic) only allowing a minimal air entrance for brake cooling.
