Castrol React SRF is the ultimate racing brake fluid. Its unique silicon ester technology prevents high temperature performance from deteriorating, due to moisture absorbtion. Its wet boiling point of 518 degrees F is vastly superior to any other racing brake fluid. Its ability to withstand temperatures up to 590 degrees F and resistance to the effects of absorbed water have established Castrol SRF as the world's premier brake fluid for motorsport and racing use.

• Dry Boiling point minimum: 590 degrees F
• Wet boiling point minimum: 518 degrees F
• Silicon ester technology allows for extended change intervals
• Compatible with all fluids meeting DOT 3, DOT 4, and DOT 5.1 standards

To maintain the functional reliability of brake systems, brake fluid must be changed according to the specifications of the vehicle manufacturer (quality and change interval). In race/track applications, it is critical that brake fluid be routinely changed, to maintain optimum performance.
