VP Racing 622 Racing Brake Fluid: Full Synthetic DOT 4

VP 622 Racing Brake Fluid is a full synthetic DOT 4 fluid engineered for high-performance and competition braking applications. Its 622°F dry boiling point and 410°F wet boiling point exceed DOT 4 minimums by a significant margin, providing the thermal headroom needed to prevent vapor lock and brake fade under sustained hard braking conditions.

Brake fade caused by fluid boiling is one of the most dangerous failure modes in performance driving. When brake fluid reaches its boiling point, it vaporizes and creates compressible gas bubbles in the lines. The result is a soft, spongy pedal that provides reduced stopping force at exactly the moment you need it most. VP 622 is formulated to stay liquid and maintain a firm pedal through repeated hard stops on track.

Frequently Asked Questions

What is the boiling point of VP 622 Racing Brake Fluid? VP 622 has a dry boiling point of 622°F (328°C) and a wet boiling point of 410°F (210°C). Both exceed DOT 4 minimum requirements. The dry boiling point applies to fresh, uncontaminated fluid. The wet boiling point reflects performance after moisture absorption, which occurs naturally over time in any glycol-based brake fluid.

Is VP 622 compatible with my stock brake system? Yes. VP 622 is compatible with all DOT 3 and DOT 4 brake systems, including vehicles equipped with ABS, traction control, and stability control. Do not use in DOT 5 (silicone-based) systems.

How often should I change VP 622 Racing Brake Fluid? For track use, change the fluid before each race season or every 2 years, whichever comes first. Glycol-based brake fluids absorb moisture over time, which lowers the wet boiling point. For heavy track use, inspect and change more frequently.

Can I mix VP 622 with my existing DOT 4 fluid? Yes. VP 622 is compatible with other DOT 3 and DOT 4 fluids. However, mixing fluids will dilute the performance characteristics of VP 622. For best results, flush the system completely before filling with VP 622.

Why does wet boiling point matter? All glycol-based brake fluids absorb moisture from the atmosphere over time. Moisture lowers the boiling point of the fluid. The wet boiling point reflects performance after moisture absorption, which is the real-world condition your fluid operates in after months of use. VP 622's 410°F wet boiling point keeps performance high even as the fluid ages.
