AP Racing - PRF 660 Racing Brake Fluid
AP Racing Brake Fluids have been developed specifically for use under the arduous conditions encountered at the highest levels of motorsport. All AP Racing Brake Fluids are compatible with all hydraulic brake systems designed to conform to S.A.E. J1703 requirements.
AP Racing PRF660 fluid has a dry boiling point of 320°C (608°F), 20°C higher than some other leading brands. PRF660 has advanced moisture resistance properties, low levels of viscosity (for ease of bleeding), low levels of compressibility and meets DOT4 specifications.
PRF660 is suitable for all top levels of motorsport where abnormal temperatures are experienced. It should be noted that before using PRF660 fluid, any existing brake fluid should be drained completely from the brake system. The system should be thoroughly purged with new PRF660 and can be filled completely with new PRF660.
- 'Typical' New Dry Boiling Point in excess of - 325°C (617°F)
- 'Wet' E.R. (Equilibrium Reflux) Boiling Point - 204°C (399°F)
