DOT 4 100% Synthetic Brake Fluid *NON-SILICONE MOTUL RBF 600
Very high boiling point brake fluid for hydraulic brake and clutch systems. Specially designed to resist high temperatures in racing actuated - brake (steel or carbon) and clutch systems.
Dry boiling point 312 °C / 593 °F
Wet boiling point 216 °C / 420 °F (This wet boiling point of a brake fluid is the more important number in "real world" use.)
Brake fluids have the properties to absorb humidity contained in the air, which reduces their boiling points and consequently, their performance. The wet boiling point is representative of the fluid after one year of use. The wet boiling point is measured by humidifying the product with about 3.5% of water.
If you're doing a standard fluid bleed, 2-3 bottles should be sufficient. If you're replacing any parts that require a complete drain and refill of the system (e.g. Line/Caliper upgrades) 3-4 bottles may be necessary.
