Motul Brake Fluids for the street or the race track Motul lubricants protects and takes care of you and your vehicle. From engine and transmission oils, to coolant and brake fluids, Motul offers you a huge selection of products to suit almost any application. The Motul range of 100% synthetic brake fluids comprises of 5 different options which are specifically engineered for the highly-developed vehicles of today, including: • RBF (Racing Brake Fluid) 600 and 660 Factory Line; • DOT 3&4, DOT 4 and DOT 5.1 Brake Fluids. The RBF 600 Factory Line and RBF 660 Factory Line are a poly glycol-based brake fluid designed for the most demanding racing conditions. Poly glycol-based brake fluids are less compressible compared to those that are silicone-based even when heated, which prevents a spongy-feeling brake pedal in instances of long and hard brake application. Both RBF 600 and RBF 660 Factory Line are compatible with all types of hydraulic-actuated brake and clutch systems requiring a non-silicone synthetic fluid. Developed to resist high temperature and wet-weather conditions with a high dry boiling point of 312°C and a wet boiling point of 216°Cfor extreme thermal resistance and stability, RBF 600 Factory Line is specifically designed to resist the high temperatures of racing brakes.Itis superior to conventional DOT 5.1 (non silicone-based), DOT 5 and conventional DOT 4 (silicone-based) brake fluids, which ensures effective braking is maintainedat all times throughout races. RBF 660 Factory Line features a dry boiling point of 325°C, higher than RBF 600 Factory Line. It isdesigned to resist the extreme temperatures generated in carbon and ceramic racing brakesystems, which can rapidly rise to over 900°C in extreme conditions,however it can also be used with conventional steel brake discs. RBF 600 and RBF 660 Factory Linegreatly exceeds the performance of DOT 3, DOT 4 and DOT 5.1 standards.Combined with their outstanding anti-vapour lock performance, RBF 600 and RBF 660Factory Line have become well-trusted brake fluids in many races. RBF Factory Line brake fluids should not be mixed with brake fluids of lower performance, particularly silicone-based or mineral-based (LHM) brake fluids. Motul DOT 3&4 Brake Fluid is a polyglycol-based brake fluid designed for normal driving andin all types of applications including hydraulic-actuated brake and clutch systems meeting DOT 4 and DOT 3 manufacturer’s recommendations. The dry and wet boiling points of 245°C and 155°C respectively is superior to regular DOT 3 and DOT 4 brake fluids, which allows DOT 3&4 to last longer in your vehicle. It is also perfectly neutral and anti-corrosive, so you can be sure the seals in your vehicle’s braking system won’t suffer as a result. Motul DOT 5.1 Brake Fluid is a polyglycol-based brake fluid for all types of hydraulic-actuated brake and clutch systems in accordance with DOT 3, DOT 4 and DOT 5.1 manufacturer’s recommendations. It maintains a higher dry and wet boiling point of 272°C and 185°C respectively compared to DOT3&4 and DOT 4 brake fluids. The lower viscosity of 820mm2/s allows for easier fluid circulation in the brake lines,making it particularly suited foranti-lock braking systems (ABS) as well as heavy-duty uses such as fleet vehicles or trucks. Motul DOT 3&4, DOT 5.1 and RBF 600 and 660 is mixable with other non silicone-based brake fluids. For more information on the full range of Motul Brake Fluids
