Motul RBF 660 racing brake fluid, 0.5 L

Motul RBF 660 racing brake fluid, 0.5 L

Motul
Why we love it
  • Exceeds DOT performance standards.
  • Efficient in wet conditions.
  • Withstands high racing temperatures.
Main Highlights
  • For all brake and clutch hydraulic systems where a non-silicone synthetic fluid is recommended. Specially designed to withstand the high temperatures of racing brake hydraulics (steel or carbon) and clutches. Exceeds DOT 3 and DOT 5.1 standards, except for viscosity at -40°C / -40°F.
  • Provides better aerodynamic performance by reducing air intake for brake cooling in vehicles. Efficient in wet conditions: The very high wet boiling point of MOTUL RBF 660 FACTORY LINE (204 °C/399 °F) is higher than that of conventional non-silicone based DOT 5.1 (180 °C/356 °F mini) and DOT 4 (155 °C/311°F mini) brake fluids and therefore maintains braking efficiency under wet conditions.
  • Motul RBF 660 factory line (dot 4) 0. 5 litres

  • Designed for extreme conditions.
Main Highlights
  • Product Performance Claims JIS K 2233 Class 4 SAE J1703 SAE J1704 ISO 4925 Class 4 FMVSS 116 DOT 4
  • Description Castrol Brake Fluid DOT4 is a high boiling synthetic brake fluid which far exceeds the requirements of the SAE J1703,SAE J1704, FMVSS 116 DOT 4 , ISO 4925 and Jis K 2233 specifications. Castrol Brake Fluid DOT4 is designed for use in all brake systems particularly those which are exposed to extreme conditions.
  • Application This product has been formulated from mixed polyalkylene glycol ethers and borate esters together with other high performance additives and inhibitors which give ultimate system protection against the effects of corrosion and high temperature vapour lock.
  • Conditions of Use Castrol Brake Fluid DOT4 should not be used in braking systems for which a mineral oil based fluid is recommended (for example some Citreon systems for which Castrol LHM plus is suitable and Rolls Royce vehicles for which Castrol CHSMO Plus is approved.
  • Storage All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and the obliteration of drum markings. Products should not be stored above 60°C, exposed to hot sun or freezing conditions.
