Brake and Clutch Fluid DOT 4 is an advanced, non-petroleum automotive brake fluid designed for use in conventional hydraulic brake and clutch systems, particularly in severe service conditions or where DOT 4 fluids are recommended. Provides an additional safety margin against “vapor lock” compared with brake fluids meeting less stringent specification requirements.
For vehicles operating in extreme service conditions, or where a DOT 5.1 fluid is specified, Caltex Brake and Clutch Fluid DOT 5.1 is recommended.
Not to be used in systems designed for mineral oil based fluids (LHM), e.g., certain Citroen models and many off-highway vehicles and tractors, or where Silicone -type DOT 5 fluids are recommended.
