The brakes of your vehicle are one of the most critical safety features, and the brake fluid plays a vital role in ensuring their proper functioning. Brake fluid is a hydraulic fluid that transfers the pressure from the brake pedal to the brake calipers, which then apply pressure to the brake pads to slow down or stop the vehicle. The quality of the brake fluid can significantly impact the performance and safety of your vehicle’s brakes. With so many brands and types of brake fluid available in the market, it can be overwhelming to choose the best one. In this article, we will explore who makes the best brake fluid and what factors to consider when selecting the right one for your vehicle.

What to Look for in a Brake Fluid
When selecting a brake fluid, there are several factors to consider. The most important one is the type of brake fluid. There are three main types of brake fluid: DOT 3, DOT 4, and DOT 5.1. DOT 3 is the most common type and is suitable for most passenger vehicles. DOT 4 is more advanced and provides better performance in high-temperature conditions. DOT 5.1 is a silicone-based fluid that is designed for use in high-performance vehicles.
Another important factor is the boiling point of the brake fluid. The boiling point is the temperature at which the brake fluid starts to vaporize. A higher boiling point means that the brake fluid can withstand higher temperatures without losing its effectiveness. Look for a brake fluid with a boiling point of at least 300°F (149°C) for normal driving conditions and 400°F (204°C) for high-performance driving.
Other factors to consider include the viscosity of the brake fluid, which affects its flowability and lubricity, and the additive package, which includes corrosion inhibitors and anti-foaming agents. Some brake fluids may also have additional features such as rust inhibitors or UV stabilizers.

FAQs
Q: What is the difference between DOT 3 and DOT 4 brake fluid?
A: DOT 3 brake fluid is designed for use in passenger vehicles and has a boiling point of around 300°F (149°C). DOT 4 brake fluid is designed for use in high-performance vehicles and has a boiling point of around 446°F (233°C). DOT 4 brake fluid is more advanced and provides better performance in high-temperature conditions.
Q: Can I use DOT 5.1 brake fluid in my passenger vehicle?
A: No, DOT 5.1 brake fluid is designed for use in high-performance vehicles and is not suitable for use in passenger vehicles. DOT 5.1 brake fluid has a higher viscosity and is more prone to foam than DOT 3 or DOT 4 brake fluid.
Q: How often should I change my brake fluid?
A: The recommended interval for changing brake fluid varies depending on the manufacturer’s recommendations and the type of brake fluid used. Generally, it is recommended to change brake fluid every 30,000 to 50,000 miles (48,000 to 80,000 km) or as recommended by the manufacturer.
Q: Can I mix different types of brake fluid?
A: No, it is not recommended to mix different types of brake fluid. Each type of brake fluid has its own unique properties and is designed for use in specific applications. Mixing different types of brake fluid can result in unpredictable performance and may compromise the safety of the brake system. (See Also: Why Do I Hear a Grinding Noise When I Brake?
