RBF660 is 100% Synthetic Racing DOT4 Brake Fluid.

Very high boiling point of 325°C / 617°F. Suitable for all hydraulic actuated brake and clutch systems requiring non-silicone synthetic fluid. Specially designed to resist to extreme temperature generated by racing carbon and ceramic brakes allowing minimizing air entrance for brake cooling. Can be also used with conventional steel discs and clutch systems actuators. Widely exceeds DOT 3, DOT 4 and DOT 5.1 standards (except for DOT 5.1 viscosity at – 40°C). Part no 101666.
