Performance Friction RH665 racing brake fluid. a 100% synthetic, DOT 4 specification brake fluid, with a very high dry boiling point of 617ºF (325ºC), especially formulated for use in extreme temperature environments, such as in carbon and ceramic braking systems used in professional motorsport. Approved by Porsche Motorsport for racing use and has the highest guaranteed minimum Dry Boiling Point (325°C) of any DOT 4 Brake Fluid, although typical values for PFC RH665 are invariably higher than 325°C and a similar situation applies to the Wet Boiling Point, where RH665 is guaranteed to be above 195°C. As with all high performance braking systems, to ensure ultimate performance and reliability, you must flush through with fresh RH665, to remove any residual fluid in the system. Bottles are vapour sealed for freshness.
