Liqui Moly Brake Fluid DOT 5.1 EV - 500ML

No, it is critical that this brake fluid is used alone. Mixing it with other brake fluids, especially mineral-based or conventional DOT 3/4 fluids, can compromise its unique properties, such as low electrical conductivity and high boiling point, and lead to system damage.

This fluid meets DOT 3 and DOT 4 specifications, so it can be used in systems that require them. However, its specialized low-conductivity formulation is primarily beneficial for modern vehicles, particularly EVs. Always confirm your vehicle manufacturer's recommendation.

The recommended interval for changing brake fluid is typically specified by the vehicle manufacturer, usually every 1 to 3 years, or based on mileage. This fluid's advanced properties help maintain performance longer, but regular replacement is still essential due to moisture absorption.

Low electrical conductivity means the fluid is less likely to conduct electricity. In an electric vehicle's high-voltage system, this helps prevent unintended electrical currents from flowing through the brake fluid, which could interfere with system operation or cause damage.

DOT 5 fluid is silicone-based and not compatible with DOT 3, 4, or 5.1 fluids. DOT 5.1 is glycol-ether based, like DOT 3 and 4, but offers higher boiling points and lower viscosity than standard DOT 4. Liqui Moly DOT 5.1 EV is a specialized version of DOT 5.1.

This product is typically available through automotive parts retailers, specialized online stores, and some mechanic shops that carry Liqui Moly products.

This fluid meets or exceeds FMVSS 116 DOT 3, DOT 4, DOT 4 LV, DOT 5.1, DOT 5.1 LV; ISO 4925 Class 3, Class 4, Class 5.1, Class 6, Class 7; and SAE J 1703, J 1704.

This could indicate air in the brake lines or that the fluid has absorbed excessive moisture, lowering its boiling point. Bleed the brake system thoroughly. If the issue persists, replace the brake fluid.

Check the brake fluid level in the reservoir. If low, top up and check for leaks. If the fluid level is correct, the issue may be with a sensor or a more significant system problem; consult a qualified mechanic.

Ensure the correct fluid type (DOT 5.1 EV with low-temperature viscosity) is used and that the system is free of air. If the fluid is old and has absorbed moisture, it may freeze or become too viscous. Replace the fluid.

This might be due to using an incompatible fluid or fluid that has degraded. Flush the system and refill with the correct Liqui Moly DOT 5.1 EV fluid. Inspect components for damage and replace as necessary.
