This provides: - Optimal protection against corrosion - Reduction of vapor formation ### Compatibility and applications Castrol React Performance DOT 4 is fully compatible with other brake fluids that meet the FMVSS 116 DOT 3, DOT 4, and DOT 5.1 standards. It is recommended not to mix the product with other brake fluids to maintain its high performance. Replace the brake fluid according to the vehicle manufacturer's recommendations; in the absence of specific guidelines, a replacement interval of two years is advised. ### Specifications and approvals This brake fluid meets and exceeds the following specifications: - FMVSS 116 DOT 4 - ISO 4925 Class 4 - JIS K2233 - SAE J1703 - SAE J1704 ### Important usage conditions Note: Castrol React Performance DOT 4 should not be used in braking systems for which mineral oil-based products are recommended, such as certain Citroën systems for which Castrol LHM Plus is suitable, and Rolls Royce vehicles for which Castrol CHSMO Plus is approved. Avoid contact with paintwork; if contact occurs, rinse immediately with water without rubbing. ### Typical properties - Kinematic viscosity at -40°C: 1200 mm²/s - Density at 20°C: 1.07 g/ml - Wet boiling point (WRBP): minimum 180°C - Dry boiling point (ERBP): minimum 260°C - Appearance: yellow, clear and transparent - pH value: 7.2 ### Storage and handling Preferably store the brake fluid under cover. If stored outdoors, place the drums horizontally with the bungs below the oil level to prevent water ingress and label fading. Avoid storage above 60°C and exposure to direct sunlight or frost. ### Packaging Castrol React Performance DOT 4 is available in various packaging sizes, including 1 liter and 60 liters, to meet different needs. ## Breadcrumbs -
