K2 Brake Fluid DOT 4 is a synthetic brake fluid developed for modern braking systems that require high thermal stability and reliable corrosion protection. The product meets the DOT 4 standard and is suitable for passenger cars, light commercial vehicles, and motorcycles with hydraulic braking systems.

With a dry boiling point of 230 °C, the fluid helps maintain stable braking performance even during intensive driving and at high operating temperatures. See more K2 products for car care in our range.

What is Brake Fluid DOT 4 and why choose it?

Brake fluid is a hydraulic fluid that transfers force within a vehicle's braking system. DOT 4 is a common standard for modern vehicles and offers a higher boiling point compared to DOT 3, which reduces the risk of vapour formation in the brake lines under heavy load. K2's synthetic formulation also provides active corrosion protection for metal components within the braking system, extending the system's service life.

Synthetic brake fluid absorbs moisture more slowly than conventional alternatives, meaning the boiling point is maintained at a safe level for longer between service intervals.

Where is this product suitable?

• Passenger cars and SUVs with hydraulic disc brakes
• Light commercial vehicles and vans
• Motorcycles with DOT 4-compatible braking systems
• Vehicles used during intensive driving or in hilly terrain
• Workshops and vehicle preparation centres carrying out brake servicing

Frequently Asked Questions (FAQ)

Is K2 Brake Fluid DOT 4 compatible with all vehicles that require DOT 4?

Yes, K2 Brake Fluid DOT 4 is compatible with all vehicles whose manufacturer specifies the DOT 4 standard for the braking system. This includes passenger cars, light commercial vehicles, and motorcycles with hydraulic brakes. Always check the vehicle's service manual before topping up, and do not mix DOT 4 with DOT 5 (silicone-based) without flushing the system.

What is the boiling point of K2 Brake Fluid DOT 4 and why does it matter?

K2 Brake Fluid DOT 4 has a dry boiling point of 230 °C. A high boiling point is critical for braking safety – if the fluid boils, vapour bubbles form within the system, which severely reduces braking effectiveness (known as vapour lock). At 230 °C, K2's formulation provides a sound safety margin even during intensive driving, for example on hilly roads or during repeated heavy braking.

What sets K2 Brake Fluid DOT 4 apart from other brake fluids on the market?

K2 Brake Fluid DOT 4 is a synthetic formulation with integrated corrosion protection, which shields metal components in the braking system from deterioration. Compared to simpler mineral-based alternatives, the synthetic base offers better stability over time and slower moisture absorption. The product meets the DOT 4 standard and is developed to perform reliably in modern braking systems with demanding performance requirements.
