Castrol SRF Brake Fluid is a high performance brake fluid of special value in competitive motor sport where extreme braking conditions are encountered. It has been especially formulated to maximize braking performance under arduous competitive conditions. In order to achieve the optimum benefits in such applications, patented silicon ester materials have been employed in a unique Castrol formulation.
Product Features:
• Meets or exceeds US FMVSS 116 DOT 3 and DOT4
• Race Proven: Widely used in racing, from Formula One sports cars, to group A and 500cc Grand Prix motorcycles
• High Boiling Point: The exceptionally high dry boiling point (higher than 300°C) makes Castrol SRF ideal for use under extreme braking conditions such as rallying or racing. Castrol SRF exceeds the boiling point requirements of DOT 5 brake fluids.
• Compressibility: The compressibility of Castrol SRF is very similar to that of current DOT 3 and DOT 4 fluids. It can therefore be filled into any braking system used in motor sport with the exception of those for which mineral oil is prescribed.
Dry Boiling Point: 310°C (590°F)
Wet Boiling Point: 270°C (518°F)
