Brake fluid K2 DOT-4 1 L bottle, high boiling point hydraulic brake fluid

K2 DOT-4 brake fluid in a 1 L bottle is a hydraulic brake fluid formulated to meet DOT-4 performance requirements. It offers higher dry and wet boiling points than DOT-3 fluids, making it suitable for modern passenger cars and light commercial vehicles. The fluid is designed for use in disc and drum braking systems as well as hydraulic clutch circuits where DOT-4 specification is required, helping to maintain consistent braking performance under elevated temperatures and reducing the risk of vapor lock.

Advantages

K2 DOT-4 provides improved high-temperature resistance and stable wet boiling point characteristics compared to lower-spec fluids. The formulation supports reliable hydraulic pressure transmission, compatibility with materials commonly used in brake and clutch systems, and helps prevent performance degradation caused by moisture absorption. The 1 L bottle format is convenient for topping up reservoirs during maintenance or for small repair jobs.

Suitable for

• Passenger cars with hydraulic disc or drum brakes requiring DOT-4 fluid
• Light commercial vehicles and vans with DOT-4 hydraulic systems
• Hydraulic clutch systems specified for DOT-4 brake fluid
• Routine maintenance, bleeding and topping up brake fluid reservoirs

Key specifications

• Specification: DOT-4 hydraulic brake fluid
• Volume: 1 litre
• Suitable systems: hydraulic brakes and hydraulic clutches
• Performance: higher dry and wet boiling points versus DOT-3
• Packaging: sealed plastic bottle for maintenance use

How to use

Before use, check the vehicle manufacturer’s manual to confirm DOT-4 compatibility. Clean the area around the brake fluid reservoir cap to avoid contamination, then open the reservoir and top up or replace fluid as required. When performing a full brake fluid change or bleeding, follow proper procedures to remove old fluid and air from the system, ensuring the reservoir does not run dry during the process. Dispose of used fluid in accordance with local regulations.

Usage recommendations

Store the unopened bottle in a cool, dry place away from direct sunlight. After opening, minimize exposure to air and moisture by resealing the cap tightly and use the contents within a reasonable period to maintain fluid performance.
