Mobil Hydraulic Brake Fluid 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 and refilled with fresh fluid every two years or 40,000 Km (24,000 Miles).
  • Check Owners Operators Manual for details.
