MOTUL RBF 600 is the best brake fluid for the money we have ever used. Very high dry and wet boiling points means that this fluid will not boil under extremely heavy and extended braking. It takes about 2 bottles to change the fluid in most cars.
Extreme high performance polyglycol brake fluid. Far exceeds the standards of DOT 4. Each bottle is filled with Nitrogen, increasing shelf life and eliminating contamination while factory sealed. Extremely high dry boiling point 594F(312C) helps prevent vapor lock and brake fade during hard use, with excellent recovery time. Wet boiling point 401F(205C).
