Nobody asks for a brake fluid. They arrive at the end of a straight, hard on the pedal, and it goes further than it should.
What Heat Does to a Brake Pedal
Every hard stop pushes heat into the calipers, and the brake fluid inside them carries it. Push hard enough, for long enough, and that fluid starts to boil. Liquid doesn't compress, but vapour does — so when bubbles form, the pedal is pushing against gas instead of fluid, and the driver feels it as a soft, sinking pedal. In the worst case, called vapour lock, there's almost no pressure at all.
It usually isn't the pads or the rotors that give out first on a hot lap. It's the fluid.
Why VP Built 622
VP spent decades learning what race engines demand from fuel, then brought that same focus to oil and coolant. Brake fluid was the logical next step, and arguably the most important one. Fuel makes the power and coolant keeps the heat in check, but brake fluid is the only thing between the driver's foot and the calipers. If it fails, nothing else matters.
Racers needed a fluid that stayed stable at the temperatures real hard braking creates, not just when it's fresh out of the bottle, but after it has been in the car and absorbed moisture. That's what VP designed 622 to do. VP's own proof of it is a driver rather than a lab number: in one of VP's own films, Vaughn Gittin Jr says he trusts it.
What the Name Means
622 isn't a model number. It's the dry boiling point: 328°C (622°F). That's the temperature fresh fluid can reach before it starts to boil, and it's the number VP chose to put on the bottle.
The Number That Matters More
Brake fluid naturally absorbs moisture from the air over time, and moisture lowers its boiling point. That's why the wet boiling point, measured after the fluid has absorbed 3.7% water by volume, is the more honest test of how a fluid performs in the real world.
This is where VP 622 separates itself: a wet boiling point of 204°C (399°F), against 155°C (311°F) for standard DOT 4. That's roughly 49°C of extra margin before the fluid starts to boil, and that margin is what keeps the pedal firm on the last hard stop of the day, not just the first.

What Drivers Feel
VP 622 is built for hard racing and hard braking. It resists fade and vapour lock, and it delivers a consistent pedal that behaves in a linear, predictable way as temperatures climb. For a driver, that means the brake marker on the last lap is the same as the brake marker on the first. The pedal stays high and firm, trail braking stays precise, and confidence stays intact.
Change your fluid: Brake fluid wears out and absorbs moisture, and moisture can cause internal corrosion and, in the worst case, brake failure. Bleed and replace your fluid regularly. For racing, VP recommends bleeding the entire system with fresh fluid before each race, especially in high heat or humid conditions.
What VP Stands Behind
Every VP fluid starts with the same question: what does this engine, this car, this driver actually need at the limit? For brakes, the answer is a pedal you never have to think about. VP 622 is built so the only thing on a driver's mind in the braking zone is the corner ahead.
