- Castrol React SRF Racing is suitable for all disc and drum brake systems with the exception of those for which mineral oil is prescribed. It is miscible with all conventional fluids meeting US Federal Standards FMVSS 116 DOT 3 and DOT 4, ISO 4925 and current SAE J1703. However, mixing with conventional brake fluids will merely reduce the higher quality of Castrol React SRF Racing and therefore recommended that conventional brake fluids be drained from the system before flushing and re refilling.
