HIGHTEC BRAKE FLUID DOT 4 LV is a low-viscosity, fully synthetic high-performance brake fluid based on glycols. Its reduced viscosity allows fast pressure build-up in modern ABS and ESP systems, even in the cold, while a high boiling point keeps the pedal firm under load.

Purpose and specifications

Developed for hydraulic brake and clutch systems with ABS and ESP that require a low-viscosity DOT 4 fluid. It meets FMVSS 116 DOT 4, SAE J 1703, SAE J 1704, ISO 4925 Class 3, ISO 4925 Class 4, ISO 4925 Class 6, JIS K2233 Class 3, JIS K2233 Class 4, JIS K2233 Class 6, Ford WSS-M6C65-A2 and VW 501 14.

• 1L container for a complete system bleed and fluid change
• Low viscosity for rapid response of ABS, ESP and active safety hydraulics in cold conditions
• High dry boiling point of at least 260 C and wet boiling point of at least 170 C for vapour-lock resistance
• Corrosion and oxidation inhibitors protect cylinders, calipers and electronic control units

When to use / change?

Use it where a low-viscosity DOT 4 LV fluid with Ford or VW approval is specified, especially in vehicles with electronic stability systems. As a hygroscopic glycol fluid it should be replaced about every 2 years regardless of mileage to preserve the boiling point. It performs across the full temperature range, including cold starts. Unopened shelf life is approximately 5 years stored sealed and dry.

Frequently asked questions

What does the LV in DOT 4 LV mean?
LV stands for low viscosity, which helps ABS and ESP systems build pressure quickly in the cold.

Can I use it instead of standard DOT 4?
Use it where the maker specifies a DOT 4 LV or ISO Class 6 fluid, such as the listed Ford and VW approvals; it mixes with other synthetic glycol fluids.

How often should it be renewed?
Around every 2 years, because the fluid absorbs moisture that gradually reduces its boiling point.

Suitable for: Ford Focus, Ford Mondeo, Volkswagen Golf, Volkswagen Passat, Audi A4. Always verify the exact approval against your vehicle's owner manual before use.
