Electric & Hybrid Vehicles

Yes. Electric and hybrid vehicles typically use advanced glycol-based brake fluids such as DOT 4, DOT 5.1, or low-viscosity ESP / ISO Grade 6 fluids.

Brake fluid absorbs moisture over time, which lowers boiling point and increases corrosion risk, even in vehicles that rely heavily on regenerative braking.

Lower boiling points can lead to vapour formation under braking, reducing braking efficiency and electronic system response.

Always follow the vehicle manufacturer’s recommendation. Time-based replacement is especially important in EHV due to lower brake usage and moisture accumulation.

ESP (ISO Grade 6) fluids offer very low viscosity, enabling rapid pressure modulation required by regenerative braking, ABS, and stability control systems.

It represents the boiling point after moisture absorption and is a key indicator of long-term braking safety.

Electric and hybrid vehicles rely heavily on electronic braking systems that require fast fluid response, especially at low temperatures.

No. Reduced mechanical braking can actually increase moisture-related degradation because the fluid experiences less heat cycling.

No. DOT 5 is silicone-based and generally unsuitable for modern electric and hybrid braking systems.

Only compatible glycol-based fluids may be mixed, but this is not recommended. Performance will default to the lowest grade.

Always use the brake fluid specified by the vehicle manufacturer, typically a low-viscosity DOT 4, DOT 5.1, or ESP fluid.

No. Colour does not indicate fluid performance or condition.

Moisture enters through hoses, seals, reservoirs, and microscopic permeability over time.

Boiling creates vapour that compresses under pressure, leading to reduced braking force or failure.

Brake fluid has a long shelf life when unopened and stored correctly, but should be used promptly once opened.
