Brake Fluid K2 DOT4 Racing 250 ml bottle, brand K2, MPN T126

K2 DOT4 Racing brake fluid in a 250 ml bottle is a DOT4 specification hydraulic fluid designed for automotive braking systems in passenger cars and light vehicles. Supplied with certification, this brake fluid meets DOT4 performance requirements for viscosity, boiling point, and compatibility with common braking system materials. It is intended for topping up or replacing existing brake fluid to help maintain braking response and protect system components from moisture-related degradation and corrosion.

Advantages

This DOT4 brake fluid provides consistent hydraulic performance across typical operating temperatures and helps sustain pedal feel and braking responsiveness. Its formulation reduces the risk of vapor lock by offering a higher dry and wet boiling point compared with lower-grade fluids, and it is compatible with seals and hoses commonly used in modern brake systems. The compact 250 ml bottle is convenient for precise top-ups and small repairs without wasting excess fluid.

Suitable for

• Passenger cars and light commercial vehicles requiring DOT4 brake fluid
• Topping up brake fluid reservoirs between full brake fluid changes
• Small-scale brake system maintenance and emergency top-ups

Key specifications

• Specification class: DOT4 hydraulic brake fluid
• Volume: 250 ml
• Compatibility: formulated for use with common rubber seals and hoses in automotive brake systems
• Performance characteristics: engineered for higher dry and wet boiling points than DOT3-class fluids and stable viscosity for reliable hydraulic response
• Application type: suitable for topping up or replacing brake fluid in passenger cars and light vehicles

How to use

Before use, consult the vehicle manufacturer's service manual to confirm DOT4 compatibility and the recommended maintenance intervals. For topping up, clean the brake fluid reservoir cap area to avoid contamination, then slowly add fluid until the level reaches the specified mark. When performing a full brake fluid replacement or bleed, follow standard workshop procedures to avoid introducing air into the system and ensure correct pedal feel. Dispose of waste fluid in accordance with local regulations.

Usage recommendations

Store the bottle tightly closed in a cool, dry place away from direct sunlight and moisture. Replace the cap immediately after use to prevent moisture absorption, and do not mix with fluids of unknown specification. If in doubt about compatibility or brake system condition, consult a qualified technician.
