PFC RH665 DOT 4 Racing Brake Fluid 500ml

PFC Racing high performance brake fluids have been specially formulated for fast road, trackday, rally & race applications, where braking systems operate at very high temperatures. A complex mixture of Glycol Ether Borate Esters and Polyalkylene Glycol Ethers together with advanced corrosion inhibitors, antioxidants and other modifiers results in an exceptional brake fluid with not only a very high boiling point but which also conforms to FMVSS 116 DOT 4 and maintains its class leading viscosity, lubricity and compressibility performance at extreme temperatures to ensure braking system reliability and performance and a firm, consistent pedal.

RH665 has the highest GUARANTEED minimum Dry Boiling Point (ERBP) of any DOT 4 Brake Fluid, 325°C, to guard against vapour lock and give a firm and consistent pedal even under extreme racing conditions. Many manufacturers quote “typical” boiling points – do not be deceived, this is not the minimum specification that you could receive, it can be the result of a test on a single sample. “Typical” values for RH665 are invariably higher than 325°C, and RH605 is an equally impressive 290°C. A  similar situation applies to “Wet” Boiling Point. RH665 is GUARANTEED to be above 195°C – “typical” values are much higher and at least the equal of other leading brands. RH605 exceeds 165°C. Boiling point is of course not the whole story. With brake fluid it is essential to have the correct balance of properties to get a good overall result. Low viscosity is very important to ensure a good bleed, low compressibility is essential for a firm pedal and lubricity is vitally important for efficiency, pedal return and life of the brake system.
