Performance Friction RH665 is not the same as other Racing Brake Fluids. Specially formulated for racing applications, where braking systems operate at very high temperatures, RH665 is a complex mixture of Glycol Ether Borate Esters and Polyalkylene Glycol Ethers together with advanced corrosion inhibitors, antioxidants and other modifiers. The result is 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 Rock Hard pedal. Exceeds all DOT 3 & 4 requirements, and compatible with all DOT 3/4/5.1 fluids.

Sold in 1.057 US Pints/500mL container.

Note: Many manufacturers quote “Typical” boiling points – do not be deceived, this is not the minimum specification that you could receive. Rather, it can be the result of a test on a single sample. 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.
