Liqui Moly Brake Fluid SL6 DOT 4 is a synthetic brake fluid based on glycol ethers and their boric acid esters. It contains effective corrosion inhibitors and antioxidant additives and was specially developed to extend the operating life of components in hydraulic brake and clutch systems. Its high dry boiling point and high wet boiling point ensure safe braking even after moisture absorption over extended use. Special moisture scavengers help prevent the formation of steam bubbles.

Areas of application / use
-
Exceptionally well-suited for hydraulic brake and clutch systems where a synthetic brake fluid is prescribed.
-
Low low-temperature viscosity makes it especially suitable for brake systems with ABS/ASR/ESP/DSC.
-
Brake fluid is hygroscopic: store tightly sealed and reseal immediately after opening.
-
Replace in accordance with vehicle manufacturer specifications. Optimum performance only when used unmixed.
