100% synthetic DOT 4 racing brake fluid with a 325°C (617°F) dry boiling point — 500 ml, Made in USA
Motul RBF 660 Factory Line is a 100% synthetic, polyglycol-based racing brake fluid for all hydraulically actuated brake and clutch systems that call for a non-silicone synthetic fluid. It's specially designed to withstand the extreme temperatures generated by racing brakes, including carbon and ceramic discs, and also works with conventional steel rotors and clutch systems.
Its very high dry and wet boiling points help prevent vapour lock and brake fade, keeping the lever or pedal firm through repeated hard braking. As a DOT 4 fluid, it's also suitable for high-performance street use.
Features:
- 100% synthetic polyglycol racing brake fluid
- Dry boiling point of 325°C / 617°F, well above DOT 4 (230°C min.) and DOT 5.1 (260°C min.) requirements
- Wet boiling point of 205°C / 401°F, well above DOT 4 (155°C min.) and DOT 5.1 (180°C min.) requirements, for strong performance even after the fluid absorbs moisture
- Exceeds DOT 3 and DOT 5.1 standards (except DOT 5.1 viscosity at -40°C)
- Resists vapour lock and brake fade under extreme heat
- Suitable for carbon, ceramic and steel brake systems and hydraulic clutches

Need even more heat resistance? See Motul RBF 700 Factory Line (111257), with a 336°C dry boiling point. Do not mix with silicone-based (DOT 5) or mineral-based (LHM) fluids. Brake fluid absorbs moisture over time, so keep containers sealed and flush regularly. Always follow your vehicle manufacturer's recommendations.
