DOT-4 Brake Fluid is a glycol ether borate–based hydraulic brake fluid specifically formulated to exceed the requirements of the internationally recognised standards: FMVSS No. 116 DOT 4, SAE J1704, ISO 4925 Class 4, and JIS K2233.
Its composition and performance ensure the safe and reliable operation of vehicle braking systems, with key benefits including:
High Boiling Point – exceeds the minimum ERBP and WERBP requirements, minimising the risk of vapour lock under extreme conditions.
Optimal Viscosity – designed to maintain system responsiveness in very cold conditions, while preventing leakage and ensuring good lubricity at high temperatures.
Corrosion Inhibition – fully protects all metallic components in the braking system against corrosion and potential failure.
Rubber Compatibility – maintains correct rubber swell and hardness of all rubber parts, maximising seal life and ensuring safe operation.
Fluid Compatibility – can be safely mixed with other brake fluids meeting DOT 3 and DOT 4 specifications. Not compatible with mineral oil–based fluids.
