Product description

Brake Fluid DOT 5.1 developed for vehicles with high performance hydraulic brake systems working in severe services.


Recommended for brake circuits in all vehicles using synthetic fluids where DOT 5.1 level is required and especially for vehicles operating in very severe conditions. It is used in competition. Miscible with other synthetic fluids of chemical type such as DOT 3, DOT 4 and DOT 5.1. Not miscible with mineral base fluids of LHM type and fluids of DOT 5.1 type with silicon. Designed for vehicles fitted with modern braking and ABS systems. For superior braking in extreme conditions. Compatible with all brake systems requiring DOT 5.1 brake fluids.


  • High boiling point, far superior than DOT 4.0
  • Compatible with joints and seals to prevent fluid loss
  • Great thermal stability
