_____________________________________________________________________________________

Applications

Castrol SRF is a DOT 4 brake fluid and is of specific value in competitive motor sport applications. It is suitable for all disc and drum brake systems with the exception of those for which mineral oil is prescribed.

Castrol SRF is based on a unique silicon ester technology, exclusive to Castrol, which enables it to be an extremely high performance product. It has a typical wet boiling point of 270·C greatly in excess of the DOT 4 minimum of 155·C and its typical dry boling point of 320·C is also outstanding. Castrol SRF is of special value where extreme braking conditions are encountered.

Features / Benefits

This is an exclusive Castrol product patented in many countries. Mixing SRF and conventional brake fluid will reduce the benefits of Castrol SRF, therefore it is recommended that conventional brake fluid be drained from the system before flushing and refilling with Castrol SRF.

The properties of Castrol SRF are such that its use should be restricted to not more than eighteen months before draining and refilling.

Specifications / Performance

Castrol SRF is a high performance, synthetic brake fluid which far exceeds the requirements of the SAE J 1703, FMVSS 116 DOT 3 and DOT 4, ISO 4925, JIS K2233G specifications.
