PFC RH665 Racing Brake Fluid
RH665 is not the same as other Racing Brake Fluids. It has been specially formulated for racing applications, where braking systems operate at very high temperatures. RH665 has the highest guaranteed minimum Dry Boiling Point of any DOT 4 Brake Fluid to guard against vapour lock and give a rock hard pedal even under extreme racing conditionsl
Minimum guaranteed dry boiling point of 325°C with typical dry boiling point approaching 330°C.
RH665 also maintains its class leading viscosity, lubricity and compressibility performance at extreme temperatures, to maintain braking system reliability and performance.
For best results bleed the system with fresh fluid before each event, especially if the brakes are excessively hot and/or the conditions are humid.
RH665 can safely be mixed with other DOT 4 Brake Fluids; however this will degrade its properties.
