Fully synthetic DOT 4 brake fluid for passenger cars, commercial vehicles and machinery with high boiling point reserve and wide application range.
DOT 4 fully synthetic brake fluid is designed for hydraulic brake and clutch systems in passenger cars, commercial vehicles, buses as well as agricultural and construction machinery. The product combines solid DOT 4 performance with high reserves in dry and wet boiling points.
Especially under thermal stress, this reserve helps prevent dangerous vapor lock and maintains a stable pedal feel. This makes the brake fluid a reliable standard solution for both everyday driving and higher loads.
For vehicles without specific low-viscosity requirements, it remains a classic and versatile DOT 4 choice.
Suitable for brake and clutch systems where DOT 3/DOT 4, SAE J 1703/1704, ISO 4925 Class 3/4 or comparable specifications are required.
When is a standard DOT 4 brake fluid sufficient?
If the vehicle does not require a specific low-viscosity or racing specification.
Is DOT 4 compatible with DOT 3?
In many systems yes, but the manufacturer’s specification is always decisive.
Why are dry and wet boiling points important?
Because they determine how resistant the brake fluid is to vapor formation.

Containers of any kind should preferably be stored under cover. If stored outdoors without protection, containers should be kept horizontally to prevent water ingress and preserve label readability. Products should not be stored at temperatures above 60 °C. Protect from direct sunlight and frost. 18180 | 18255 | 31.05.2025
