What is DOT 4 Brake Fluid?
DOT 4 brake fluid is a type of brake fluid that meets the standards set by the Society of Automotive Engineers (SAE) and the Department of Transportation (DOT). It is a glycol-based brake fluid that is designed to provide superior performance and protection for modern brake systems. DOT 4 brake fluid is formulated to withstand the high temperatures and pressures generated by modern braking systems, making it an ideal choice for vehicles with high-performance braking systems.
Characteristics of DOT 4 Brake Fluid
DOT 4 brake fluid has several characteristics that make it an excellent choice for brake systems. Some of the key characteristics include:
- High boiling point: DOT 4 brake fluid has a high boiling point, which means it can withstand the high temperatures generated by modern braking systems.
- Good lubricity: DOT 4 brake fluid has good lubricity, which helps to reduce friction and wear on brake components.
- Good corrosion protection: DOT 4 brake fluid is formulated to provide excellent corrosion protection for brake components, helping to prevent damage and extend the life of the brake system.
- Good compatibility: DOT 4 brake fluid is compatible with most brake components and materials, making it a versatile choice for brake systems.
Benefits of DOT 4 Brake Fluid
DOT 4 brake fluid offers several benefits that make it an excellent choice for brake systems. Some of the key benefits include:
Improved Braking Performance
DOT 4 brake fluid is designed to provide improved braking performance by reducing the risk of brake fade. Brake fade occurs when the brake fluid becomes overheated, causing the brakes to lose their effectiveness. DOT 4 brake fluid’s high boiling point and good lubricity help to reduce the risk of brake fade, providing a more consistent and reliable braking performance.
Extended Brake System Life
DOT 4 brake fluid is formulated to provide excellent corrosion protection for brake components, helping to extend the life of the brake system. By reducing the risk of corrosion, DOT 4 brake fluid helps to prevent damage to brake components and extend the life of the brake system.

Frequently Asked Questions
Q: What is the difference between DOT 3 and DOT 4 brake fluid?
A: DOT 3 brake fluid has a lower boiling point than DOT 4 brake fluid, making it less suitable for high-performance braking systems. DOT 4 brake fluid has a higher boiling point and is designed to withstand the high temperatures generated by modern braking systems.
Q: Can I use DOT 4 brake fluid in my vehicle if it only requires DOT 3 brake fluid?
A: No, it is not recommended to use DOT 4 brake fluid in a vehicle that only requires DOT 3 brake fluid. DOT 4 brake fluid is designed for high-performance braking systems and may not provide the same level of performance and protection as DOT 3 brake fluid in a vehicle that only requires DOT 3 brake fluid.
Q: How often should I change my brake fluid?
A: The frequency of brake fluid changes depends on the type of brake fluid used and the driving conditions. It is recommended to change the brake fluid every 30,000 to 50,000 miles or as recommended by the vehicle manufacturer. (See Also: How Does Brake And Clutch Power Transmission Work? Explained)
Q: Can I mix DOT 4 brake fluid with other types of brake fluid?
A: No, it is not recommended to mix DOT 4 brake fluid with other types of brake fluid. Mixing different types of brake fluid can result in a brake fluid that does not meet the standards set by the Society of Automotive Engineers (SAE) and the Department of Transportation (DOT).
Q: What are the symptoms of low brake fluid levels?
A: Symptoms of low brake fluid levels include spongy brake pedal, reduced braking performance, and a warning light on the dashboard. If you experience any of these symptoms, it is recommended to check the brake fluid level and top it off as necessary.
