Brake fluid made of poly alkylene/glycol base and high performance additive package. Castrol Break Fluid DOT 4 is suitable for use in all brake fluid systems requiring either a DOT 3 or DOT 4. Specifications: JASO JIS K2233, SAE J1703J1704, 4925 Class 4, FMVSS DOT 4, replaces Response brake fluid DOT4

not hygroscopic, do not attack painted surfaces, aluminium, chrome and plastic parts, dry boiling point over 260°C. Not mixable with brake fluids of other specifications!

Mineral basedBrake and clutch fluid.
The low-maintenance formula does not attack painted surfaces and carbon, does not absorb moisture like DOT fluids, maintains a high boiling point and minimizes maintenance and bleeding frequency. Provides consistent lever feel, lubricates and protects seals and ensures zero fade braking performance under load. Suitable for brakes and hydraulic systems that specify Mineral Oil.
Note: Not compatible with glycol-based DOT brake fluids or DOT-filled brake systems.

Designed for very high security requirements and racing sport. Also recommended for sintered pads, dry boiling pint: higher as 300°C, wet boiling point: higher as 195°C

For use in hydraulic brake and clutch systems in vehicles, commercial vehicles and two-wheelers. The use under extreme conditions, such as in high-performance cars and racing conditions is possible. Specifications: FMVSS 116 DOT 4, ISO 4925 Class 4, JIS K2233, SAE J1703, SAE J1704, replaces Response brake fluid Super DOT4

High performance silicone-based brake and clutch fluid, developed for reliable braking power and protection of brake system components. The anti-vapour bubble formulation ensures constant reactivity by preventing evaporation and loss of viscosity. The advanced chemical composition resists corrosion and oxidation and is compatible with SBR, EPDM and natural rubber. Ideal for vehicles where brake fluid must not damage the paintwork. Only miscible with other DOT 5 silicone brake fluids, not with DOT 3, DOT 4 or DOT 5.1.
Meets and exceeds the US specification FMVSS 116 DOT 5.

High performance brake and clutch fluid for all hydraulic brake and clutch systems requiring DOT 5.1. Provides reliable and long-lasting braking performance and responsive Pedal and lever feel. The special anti-vapor bubble formulation protects against evaporation and water absorption, maintaining braking power even under extreme conditions. It also effectively protects against corrosion and oxidation and is compatible with SBR, EPDM and natural rubber seals. Miscible with DOT 3, DOT 4 and DOT 5.1 brake fluids. Not miscible with DOT 5 silicone brake fluids. Dry boiling point: 269°C, wet boiling point: 187°C
Meets and exceeds the requirements of FMVSS 116 DOT 5.1, DOT 3, DOT 4, SAE J1703, J1704 and ISO 4925 (classes 3, 4 and 5.1).

High performance brake fluid, which was specially developed for the extreme conditions in motor racing. A unique and patented Castrol formulation and the use of sophisticated materials guarantee maximum product benefits under request richest conditions. Castrol React SRF Racing exceeds US Federal Standards FMVSS 116 DOT 3 and DOT 4, ISO 4925, JIS K2233 and SAE J 1703. Specifications: FMVSS 116 DOT 3, FMVSS 116 DOT 4, ISO 4925 (Class 4), SAE J1703, JIS K2233, replaces SRF Racing brake fluid
