Our recommended racing brake fluid, especially for high heat/heavy cars. Unique fluid formulation has not just a high dry boiling point, but a very high wet boiling point. This means less frequent bleeds are necessary. Subjectively, many drivers claim improved pedal feel from switching to SRF.
Castrol SRF Brake Fluid has a wet boiling point of 518°F (270°C) which exceeds DOT 3 and 4 standards. Do not mix Castrol SRF and other brake fluids, as this will reduce the benefits of Castrol SRF. Sold in 1 liter containers (33.8 ozs.)
