Elf Frelub DOT 4 is a high performance synthetic brake fluid
It has been specially developed for hydraulic brake systems, to ensure safe braking in the most severe conditions. Suitable for use in all systems/applications requiring a DOT 4 brake fluid.

Elf Frelub DOT 4 is designed for use in :

  • All brake fluid systems in cars, motorcycles and  commercial vehicles requiring either a DOT 3 or DOT 4 product (excludes  systems where a mineral oil based fluid is specified).
  • Hydraulic clutch systems of conventional manual transmissions.
  • Drum or disc brakes, including vehicles fitted with ABS systems*

* For ABS systems, please adhere to manufacture recommendations or else consult our Lube Guide before use.

Elf Frelub DOT 4 offers the following benefits:

  • Good flow properties at low temperature and excellent performance when cold.
  • The viscosity is appropriate for normal and high temperature.
  • This fluid has a high boiling point, even after an extended period at high temperature.
  • In the presence of moisture, the fall in the boiling point remains low. This guarantees the incompressibility of the product and the safety of the user (no “vapour lock”).
  • Low hygroscopy/limited water take-up.
  • Compatible with natural and synthetic rubber parts used in the circuits.
  • Specially suited to brake circuits operating in very severe conditions.
  • FRELUB DOT 4 is perfect for all brake circuits for which the manufacturer requires a synthetic fluid that satisfies the standards SAE J 1704 and FMVSS 116 DOT 4.

IMPORTANT - This synthetic fluid is miscible with all other synthetic fluids of chemical type DOT 3, DOT 4, or DOT 5.1, except for the DOT 5 silicone fluids and the special fluids of type LHM.
