Advantages and Potential Benefits

High boiling point

Excellent corrosion protection

Extended life and reliability of brake system components



Mobil Brake Fluid DOT 4 is recommended by ExxonMobil for use in applications requiring disc, drum and anti-skid braking systems used in average to high performance vehicles requiring DOT 3 or DOT 4 level performance. Recommendations for use include:

     •  Use only in its concentrated form out of a previously unopened or well sealed container

     •  Always seal the container immediately after use as the fluid absorbs moisture from the atmosphere quite rapidly; this will reduce service life significantly.

     •  Never reuse drained brake fluid.

     •  Brake fluid can affect the vehicle paintwork, so remove spills immediately without rubbing.

     •  Brake fluid should be drained from the vehicle every two years or 40,000 Km (24,000 Miles) and refilled.

     •  Check Owners Operators Manual for details.
