What is DOT4 brake fluid?
DOT4 brake fluid, also known as DOT 4 brake oil, is a hydraulic fluid specially developed for braking systems that operate at higher temperatures. This DOT 4 brake fluid has a higher boiling point than DOT3, making it more resistant to intensive braking. This makes DOT4 brake oil extremely suitable for modern passenger cars, vehicles with ABS, and cars that are regularly subjected to heavier loads.
Why choose DOT 4 brake fluid?
Good DOT 4 brake fluid ensures a constant and immediate braking response, even at high temperatures. During braking, a lot of heat is generated, and if the brake fluid cannot handle this, vaporization can occur, leading to reduced braking power. With high-quality DOT4 brake fluid, you can prevent this risk and keep your car's braking system reliable and safe.
Which cars is DOT 4 brake fluid suitable for?
DOT 4 brake fluid is widely used in cars from Europe and Asia. Additionally, it is often the standard brake fluid prescribed by car manufacturers for:
- Cars with ABS and ESP
- Modern gasoline and diesel cars
- Hybrid vehicles
- Light commercial vehicles
Always check the car manual or the brake fluid reservoir to confirm that DOT4 brake oil is suitable for your car. DOT4 is usually mixable with DOT3, but never with DOT5.
Properties of DOT4 brake oil
DOT 4 brake oil stands out for its technical properties:
- High dry boiling point (≥ 230°C)
- High wet boiling point (≥ 155°C)
- Good corrosion protection
- Suitable for high braking loads
- Compatible with most modern braking systems
These properties make DOT4 brake fluid the most common and safe oil for daily use and sportier driving.
When to replace DOT4 brake fluid?
DOT 4 brake fluid is hygroscopic, meaning it attracts moisture. Over time, this lowers the boiling point and reduces braking efficiency. Therefore, we recommend replacing DOT4 brake fluid every 1 to 2 years. Signs that replacement is needed include:
- A spongy brake pedal
- Darkly discolored brake fluid
- Reduced braking power during intensive braking
- Regular replacement extends the lifespan of the braking system and increases safety.
Replacing DOT4 brake fluid step by step
The replacement of DOT 4 brake fluid is done as follows:
- Check if your car requires DOT4 brake oil
- Remove old brake fluid from the reservoir
- Refill with new DOT 4 brake fluid
- Bleed the brake system per wheel
- Check the brake pedal for firmness
- Take a safe test drive
