Description
 

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. It 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 FMVSS116 DOT4 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.

RH665 has the highest guaranteed minimum Dry Boiling Point (ERBP) of any DOT4 Brake Fluid, 325°C, to guard against vapor lock and give a Rock Hard pedal even under extreme racing conditions. Many manufacturers quote boiling points - do not be deceived, this is not the minimum specification that you could receive and can simply be the result of a test on a single sample. "Typical" values for RH665 are invariably higher than 325°C. A similar situation applies to Wet Boiling Point - RH665 is guaranteed to be above 195°C, with "typical" values much higher and at least the equal of other leading brands.

Boiling Point is not the whole story. It is also essential to have the correct balance of a multitude of other properties to get a good overall result. Low Viscosity is very important to ensure a good bleed, low Compressibility is essential for a pedal, and Lubricity is vitally important for efficiency, pedal return, and life of the brake system. BEWARE: Many Racing Brake Fluids do not meet the Viscosity requirements of DOT4.

RH665 Racing Brake Fluid conforms to and exceeds all aspects of the US FMVSS 116 DOT4 specification. This means that it is has been tested and is compatible with all the rubbers (SBR, EPDM, etc) and metals commonly used in brake systems and will not damage them. It also means that RH665 is entirely street legal. BEWARE: Many Racing Brake Fluids on the market do not conform to specificatíons and therefore cannot be guaranteed not to damage your brake system.

RH665 can safely be mixed with other DOT4 Brake Fluids however this will degrade its exceptional properties.
RH665 is not suitable for use in Contact with Magnesium components or in mineral oil based systems.
For best results bleed the system with fresh fluid before each event and when the brakes have been excessively hot and/or the conditions are especially humid. Always follow the vehicle manufacturers recommendations.
