The importance of brake fluid in a vehicle cannot be overstated. It plays a crucial role in ensuring the safety of the driver and passengers by providing the necessary pressure to activate the brakes. There are different types of brake fluid available in the market, each with its own set of characteristics and uses. One of the most common types of brake fluid is DOT 4, which is widely used in many vehicles. In this article, we will explore what cars use DOT 4 brake fluid, its benefits, and how it differs from other types of brake fluid.
What is DOT 4 Brake Fluid?
DOT 4 brake fluid is a type of brake fluid that meets the standards set by the U.S. Department of Transportation (DOT) for brake fluid. It is a glycol-based fluid that is designed to provide excellent braking performance in a wide range of temperatures. DOT 4 brake fluid is formulated to withstand the high temperatures generated by the brake system and to provide consistent braking performance over time.
Benefits of DOT 4 Brake Fluid
The benefits of using DOT 4 brake fluid include:
- Excellent braking performance in a wide range of temperatures
- Resistance to corrosion and degradation
- Compatibility with most brake systems
- Low viscosity for easy flow and minimal pump wear
- Good lubricity for smooth brake pad movement

Remember to always use the correct type of brake fluid for your car to ensure safe and reliable braking performance.
Frequently Asked Questions
Q: What is the difference between DOT 3 and DOT 4 brake fluid?
A: DOT 3 brake fluid is a less expensive and less effective type of brake fluid that is designed for use in older vehicles. DOT 4 brake fluid, on the other hand, is a more advanced type of brake fluid that provides better braking performance and is designed for use in newer vehicles.
Q: Can I use DOT 4 brake fluid in my car if it’s not specified in the owner’s manual?
A: No, it’s not recommended to use DOT 4 brake fluid in a car that doesn’t specify it in the owner’s manual. Using the wrong type of brake fluid can cause damage to the brake system and compromise safety. (See Also: E Brake Light on When E Brake Is Off? Common Causes Revealed)
Q: How often should I change my car’s brake fluid?
