RBF 600 Racing Brake Fluid
A DOT 4, 100% synthetic, non-silicone that endures the high temperatures common to racing brake and clutch systems.
RBF 600 has a dry boiling point of 593°F, superior to DOT 5 silicone fluids. Viscosity is lower than DOT 3 and DOT 4 fluids,
allowing easier fluid circulation in micro-valves and anti-lock systems.
