Pentosin Super DOT4 Brake Fluid (1 Liter)

Inside this 1-liter bottle is Pentosin Super DOT 4 brake fluid, a synthetic formulation that exceeds three major industry standards: FMVSS 116 DOT 4, SAE J1704, and ISO 4925 Class 4. Those ratings matter because they define the minimum boiling point, viscosity, and corrosion resistance that a brake fluid must meet, and Pentosin goes beyond all three.

Brake fluid degrades over time as it absorbs moisture from the atmosphere through brake lines and seals. As water content rises, the boiling point drops, which increases the risk of vapor lock under heavy braking. Pentosin Super DOT 4 is formulated with strong resistance to moisture absorption, which helps it hold a higher boiling point longer between fluid changes. The low-viscosity formula also provides good flow at cold temperatures, which is important for ABS systems that rely on rapid fluid movement through small channels and valves.

Pentosin is a well-known name in European vehicle maintenance, and this brake fluid is commonly used in Audi, BMW, Mercedes-Benz, Porsche, and Volkswagen models. It works equally well in any vehicle that calls for DOT 4 brake fluid.
