HIGHTEC BRAKE FLUID SUPER DOT 4 is a fully synthetic, high-performance brake fluid based on glycols. It is engineered for an elevated dry and wet boiling point, keeping the pedal firm and resisting vapour lock under heavy braking. Improved oxidation and corrosion inhibitors protect the hydraulic components in service.

Purpose and specifications

Intended for hydraulic brake and clutch systems of cars and light commercial vehicles that call for a DOT 4 grade fluid. It meets FMVSS 116 DOT 3, FMVSS 116 DOT 4, SAE J 1703, SAE J 1704, ISO 4925 Class 3, ISO 4925 Class 4, JIS K2233 Class 3, JIS K2233 Class 4 and DTFR 30B100 (ex. MB 331.0).

• 1L container for a full system bleed and brake fluid change
• High dry and wet boiling point for fade-resistant braking even when the fluid has aged
• Anti-corrosion and anti-oxidation additives protect calipers, cylinders and ABS units
• Mixable with any other fully synthetic glycol brake fluid for easy top-ups

When to use / change?

Choose it whenever a DOT 4 fluid is specified or for routine brake servicing. Because glycol fluid absorbs moisture over time, it should be replaced roughly every 2 years regardless of mileage, or sooner if the wet boiling point falls. It performs reliably across the normal automotive operating range and stays stable at high brake temperatures. Unopened shelf life is approximately 5 years when the container is sealed and stored dry.

Frequently asked questions

How often should brake fluid be changed?
About every 2 years, because glycol fluid is hygroscopic and absorbs water that lowers its boiling point.

Can I mix it with my current brake fluid?
Yes, it can be combined with any other fully synthetic glycol-based brake fluid of the same or higher specification.

Is it suitable for ABS and ESP systems?
Yes, it is formulated for modern hydraulic brake and clutch systems including those with electronic control.

Suitable for: all passenger cars with hydraulic DOT 3 or DOT 4 brake and clutch systems. Always verify the exact approval against your vehicle's owner manual before use.
