Product description

Xtreme BRAKE FLUID DOT 4 is a synthetic brake fluid for modern brake systems.  This product gives higher performance compared to the DOT 3 brake fluids.

Xtreme BRAKE FLUID DOT 4 shows the following features:

  • High boiling point / low vapour pressure,
  • Satisfactory viscosity over a wide temperature range,
  • Appropriate fluidity at low temperatures,
  • Good stability and properties retention,
  • Adequate compatibility with rubber,
  • Satisfactory lubrication performances,
  • Good compatibility with the various metals in the brake system,
  • Miscibility with other approved fluids of the same type.

The water tolerance is very important for the above product as a small amount of water in unavoidably picked up in service. The presence of water lowers the boiling point and increases the possibility of unsatisfactory brake performance due to vapour locking.

Xtreme BRAKE FLUID DOT 4 continues to operate satisfactorily even with limited water contamination: its boiling point does not fall below 155 °C in wet conditions.

Application

Xtreme BRAKE FLUID DOT 4 is suitable for use in passenger cars, motorcycles and commercial vehicles, particularly in disc, drum and anti-skid braking systems requiring DOT 3 or DOT 4 level performance.

Xtreme BRAKE FLUID DOT 4 has a density higher than water.  It is hygroscopic and therefore it must be preserved in closed containers.
