Purpose and Specifications

Discover the reliable K2 DOT4 5L Brake Fluid, a budget-friendly, fully synthetic solution designed for brake and clutch systems in everyday cars, trucks, and heavier vehicles. This 5-liter canister (EAN: 5906534003430, Manufacturer code: T114) delivers consistent braking power with a high boiling point up to 230°C dry and 155°C wet, preventing brake fade during hard stops or hot weather drives.

It stays fluid in cold temps down to -40°C for smooth pedal feel in winter, mixes safely with DOT3 fluids, and protects seals and metal parts from corrosion without damaging your system. Perfect for ABS-equipped cars and European models, it boosts safety on highways or loaded hauls.

When to Use / Replace?

Use K2 DOT4 in any vehicle calling for DOT4 or DOT3 fluid, especially if you tow trailers, drive in mountains, or push high speeds where heat builds up. Replace every 2 years or 40,000 km (whichever comes first) since it absorbs moisture over time, which lowers performance and risks spongy brakes.

Also swap it if the pedal feels soft, during routine service, or after sitting unused for months. Shelf life is 3-5 years unopened in a cool, dry spot.
