81 visit www.apracing.com for installation drawings & up to date product range details Radi-CAL™ BRAKE FLUIDS AP Racing’s established and re-branded, range of brake & clutch fluids embrace our Radi-CAL™ philosophy. Following the successful launch of Radi-CAL™ R4 racing fluid, AP Racing chose to re-align its full range of fluids by re-naming PRF660, 600, 551 and Formula Dot 5.1 and changing the bottles and caps (see details below). NO alterations have been made to the actual brake and clutch fluids themselves. All AP Racing brake fluids have been developed for use under arduous conditions encountered at all levels of motorsport and performance road environments and are compatible with all AP Racing products, plus conventional hydraulic brake systems designed to conform to S.A.E J1703 & J1704 requirements. Each brake and clutch fluid is supplied in heat sealed 500ml bottles. ANSWERS TO FREQUENT QUESTIONS ◘ All AP Racing Brake Fluids are Polyalkalene Glycol Ether based, not a silicone based fluid. AP Racing do not sell and do not recommend using a silicone based brake fluid with any of its products. ◘ R1, R2, R3 and R4 brake fluids are intended for competition use only. ◘ AP Racing recommend Factory R Dot 5.1 for road use. ◘ Colour variations may occur in brake fluid due to its manufacturing process. This has no effect on the quality and performance of the product. ◘ The recommended shelf life of an unopened fluid bottle is 18 months. AP Racing recommend any fluid manufactured after that time to be disposed of, and not used. Radi-CAL™ R3 BRAKE FLUID ◘ PRF660 , Re-branded as - Radi-CAL™ R3 - Silver Bottle with Yellow Cap. ◘ Part Number - CP4660-20 (Case of 20x500ml bottles) ◘ ‘Typical’ Boiling Points - New Dry 325°C - ‘Wet’ E.R. 195°C AP Racing’s R3 has a dry boiling point of 325°C (608°F) and has been developed for racing use only. R3 has advanced moisture resistance properties, low levels of viscosity (for ease of bleeding), low levels of compress- ibility and meets DOT4 specifications. R3 is suitable for all top levels of motorsport where abnormal temperatures are experienced and with the introduction of an inhibitor, can now be used with magnesium components Note: R3 can be mixed with other DOT4 racing brake fluids, but for maximum product performance the brake system should be thoroughly purged with R3 fluid. Radi-CAL™ R2 BRAKE FLUID ◘ 600 , Re-branded as - Radi-CAL™ R2 - Silver Bottle with Blue Cap. ◘ Part Number - CP3600-20 (Case of 20x500ml bottles) ◘ ‘Typical’ Boiling Points - New Dry 312°C - ‘Wet’ E.R. 195°C AP Racing’s R2 fluid has a dry boiling point of 312°C and has been specially developed to provide outstanding performance for racing applications where braking systems operate at high temperatures. R2 fluid also conforms to and exceeds DOT4 specifications, but should not be used with components made from magnesium. Note: R2 can be mixed with DOT4 racing brake fluids, but for maximum product performance the brake system should be thoroughly purged with R2 fluid. Radi-CAL™ R1 BRAKE FLUID ◘ 551 , Re-branded as - Radi-CAL™ R1 - Silver Bottle with Black Cap. ◘ Part Number - CP7551-20 (Case of 20x500ml bottles) ◘ ‘Typical’ Boiling Points - New Dry 269°C - ‘Wet’ E.R. 140°C R1 is a brake and clutch fluid suitable for all forms of motorsport and conforms to FMVSS 116 DOT3 specification. R1 is magnesium compatible and has a higher boiling point than normal brake fluids intended for road use. FACTORY R DOT 5.1 BRAKE FLUID ◘ Formula Dot 5.1 , Re-branded as - Factory R Dot 5.1 - Yellow Bottle with Yellow Cap. ◘ Part Number - CP4510-20 (Case of 20x500ml bottles) ◘ ‘Typical’ Boiling Points - New Dry 269°C - ‘Wet’ E.R. 180°C Factory R DOT 5.1 is AP Racing’s high performance, non silicone based, brake and clutch fluid. Factory R DOT 5.1 is recommended for use in the hydraulic brake and clutch systems of all cars, for which a non- petroleum based fluid is specified. Suitable for high performance applications including vehicles fitted with ABS and ESP is suitable for road and track day use. WARNINGS ◘ Whilst AP Racing race brake fluids are compatible with DOT3 and DOT4 Polyalkalene Glycol Ether based racing fluids, it is recommended that only one type of fluid is used in a system. When changing over from one of these fluids types to another, a thorough flush through with new fluid is sufficient. ◘ DO NOT USE R4 and R2 fluid in contact with any type of magnesium com- ponents (e.g. Gearbox / Clutch components) as a chemical reaction is caused, resulting in gases being generated. This will prevent the clutch hydraulics from working efficiently and may damage the magnesium components. ◘ Note: For high temperature brake applications using magnesium, AP Racing recommends R3 ◘ To obtain the best performance from racing brake systems, bleed the system thoroughly, immediately prior to each event, using AP Racing brake fluid from a new sealed bottle. This is particularly important in wet or humid conditions or when the brakes are excessively hot. Always use fresh fluid and replace bottle cap when not in use. Never re-use brake fluid. The use of a high temperature fluid should not be used as a substitute for proper brake cooling. Brake tempera- tures can be determined using AP Racing temperature stickers (CP2650-11) and thermal paints (Kit number, CP2649-1 or -5). ◘ AP Racing brake fluid contains Polyalkalene Glycol Ethers. Keep out of reach of children. ◘ Never transfer to unmarked jars or bottles. ◘ Harmful if swallowed. ◘ Avoid excessive skin contact. Flush affected eyes with water and seek medical aid. ◘ Brake fluids will damage vehicle paint work if spilled. Radi-CAL™ R4 BRAKE FLUID ◘ Part Number - CP6005-20 (Case of 20x500ml bottles) ◘ ‘Typical’ Boiling Points - New Dry 340°C - ‘Wet’ E.R. 195°C Radi-CAL™ R4 has been designed to perform better than any other product at the extremes of heavy duty braking performance, in the top levels of racing. With the highest dry boiling point of any racing brake fluid currently available, at 340°C (644°F) , R4 stands alone. With outstanding resistance to vapour lock / pedal fade under the most exacting conditions. A higher vapour lock point means a firmer brake pedal at the extremes of brake temperature. Enhanced lubricity, means this fluid is an even better lubricant than R3, itself a market leader. This helps the life of the metal moving parts of the brake system and increases system efficiency. Note: R4 can be mixed with DOT3 and DOT4 racing brake fluids, but for maximum product performance the brake system should be thoroughly purged with R4 fluid.
