Performance Friction RH665 Racing Brake Fluid



This product is on backorder and will ship when available.

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.
