Street Legal Synthetic DOT 4 Brake Fluid is a premium, high-boiling point, glycol-based brake fluid for use in disk, drum and ABS braking systems. It is designed to extend the life and reliability of braking systems and engineered for optimum brake performance under severe braking pressure, including high-performance racing and power sports applications.
VP Racing Fuels’ 622 is a DOT 4 brake fluid. They design fully-synthetic fluid for the demands of hard racing and the hard braking that comes with it. However, it's engineered to use in both autos and powersport applications. VP 622 maintains stability under high temperatures. Moreover, it is the highest boiling point DOT 4 fluid. Wet boiling point is the temperature when brake fluid begins to boil after it has absorbed 3.7% water by volume. Additionally, it resists vapor lock and fade while delivering a better pedal feel.
Brake fluid wears out over time and it naturally absorbs moisture. For this reason, it's critical to periodically change it. Maintaining your brake system is crucial for the health and performance of both your vehicle and your safety. Moisture can cause internal corrosion in multiple components of a brake system, leading to expensive repairs, or worse, brake failure.
