Pyroil DOT 4 brake fluid is specially designed for vehicles with anti-lock (ABS), disc or drum braking systems and is compatible with systems requiring both DOT 3 and DOT 4 brake fluid. By maintaining a high dry boiling point, Pyroil DOT 4 brake fluid effectively reduces the risk of fluid evaporation. The low moisture formula ensures maximum braking performance and the addition of corrosion inhibitors protects and prolongs the life of brake system components.
