Chempol Brake Fluids (Brake Fluid Dot 3, 4 & 5.1)

CHEMPOL Brake Fluids are premium quality, non-silicone, non-mineral/petroleum based, fully synthetic brake fluid designed for use in a wide range of brake and clutch applications. It offers superior dry and wet boiling points and maintains viscosity in cold and hot environments.



Recommended for re-fill or top-up of brake and clutch systems in passenger cars, 4WD’s, motorcycles, light and heavy-duty commercial vehicles, mining, construction and agricultural equipment that require a non-petroleum-based brake & clutch hydraulic fluid.

DOT 5.1 Suitable for use where the vehicle manufacturer specifies either DOT 3, DOT 4, or DOT 5.1 fluids. It is also suitable for use with all types of seals, hoses and other brake and clutch system parts. Low viscosity (at -40C), for faster fluid circulation in micro-valves of ABS systems

DOT 4 Suitable for use where the vehicle manufacturer specifies DOT 3 or DOT 4 brake fluid. Better performance for life of fluid compared to DOT 3 fluids.

DOT 3 Suitable for use where the vehicle manufacturer specifies DOT 3 brake fluid.

NOTE: Intermixing of brake fluids of different grades is not recommended. Intermixing may impact the braking performance of some brake systems. This product is not miscible with silicone-based brake fluids. This product is not compatible with any mineral or synthetic oil-based fluids

Product Benefits

  • Excellent braking response due to high boiling point of fluid.
  • A high wet boiling point ensures long-term retention of fluid performance.
  • Better performance for the life of the fluid.
  • Compatible with all common brake system materials
  • Borate esters to scavenge water and maintain ERBP as the fluid ages
  • Anti-corrosion properties: complete brake system protection.
  • Elastomer compatibility: no leakage or fluid losses.

Storage Stability

Storage time is up to three years in sealed, metal, bulk containers. Protection should be provided to prevent any moisture contamination. Moisture contamination will result in a 5-10 °C boiling point drop for each O.1% of water absorbed.
