The importance of brake fluid in a vehicle’s braking system cannot be overstated. It plays a crucial role in ensuring the safe and efficient operation of the brakes, and its quality can have a significant impact on the overall performance and safety of the vehicle. With so many different types of brake fluid available, it can be difficult to determine which one is best for your vehicle. In this article, we will explore the six desirable properties of brake fluid and what they mean for your vehicle’s braking system.
Property 1: Boiling Point
The boiling point of brake fluid is one of the most important properties to consider when selecting a brake fluid. The boiling point is the temperature at which the brake fluid begins to vaporize, which can lead to a loss of braking performance and potentially cause the brakes to fail. A higher boiling point indicates a brake fluid that is more resistant to heat and can withstand the high temperatures generated by the brake system.
Brake fluids with a higher boiling point are typically more expensive than those with a lower boiling point, but they offer better performance and longer lifespan. In general, a brake fluid with a boiling point of at least 260°F (127°C) is considered to be of high quality and suitable for most vehicles. However, some high-performance brake fluids may have a boiling point of up to 300°F (149°C) or more.
Why is Boiling Point Important?
The boiling point of brake fluid is important because it determines the fluid’s ability to withstand the high temperatures generated by the brake system. When the brake fluid boils, it can cause the brakes to become less effective, leading to a loss of braking performance and potentially causing the brakes to fail. A brake fluid with a higher boiling point is less likely to boil, even in extreme temperatures, which makes it a safer and more reliable choice for your vehicle.
Property 2: Viscosity
Viscosity is another important property of brake fluid that affects its performance and lifespan. Viscosity is a measure of the fluid’s thickness and resistance to flow. Brake fluids with a higher viscosity are thicker and more resistant to flow, which makes them better suited for use in cold temperatures. However, they can also be more prone to degradation over time, which can reduce their performance and lifespan.
Brake fluids with a lower viscosity are thinner and more prone to flow, which makes them better suited for use in hot temperatures. However, they may not provide the same level of braking performance in cold temperatures. In general, a brake fluid with a viscosity rating of 3.5-4.5 cSt (centistokes) is considered to be of high quality and suitable for most vehicles.
Why is Viscosity Important?
Viscosity is important because it affects the brake fluid’s ability to flow through the brake system and reach the brake pads. Brake fluids with the right viscosity rating can provide the best possible braking performance, regardless of the temperature. If the viscosity rating is too low, the brake fluid may not provide enough braking power, while a viscosity rating that is too high may cause the brakes to become less effective.
Property 3: Corrosion Inhibition
Corrosion inhibition is another important property of brake fluid that affects its performance and lifespan. Brake fluids with corrosion inhibition properties are designed to prevent corrosion and rust from forming on the brake system components, which can cause the brakes to fail prematurely. Corrosion inhibition is particularly important in areas where the brake system is exposed to moisture, salt, or other corrosive substances. (See Also: How to Check Brake Light Fuse?

Brake fluids with corrosion inhibition properties typically contain additives such as rust inhibitors and corrosion inhibitors. These additives help to prevent corrosion and rust from forming on the brake system components, which can extend the lifespan of the brakes and reduce the risk of failure.
Why is Corrosion Inhibition Important?
Corrosion inhibition is important because it helps to prevent corrosion and rust from forming on the brake system components. Corrosion and rust can cause the brakes to fail prematurely, which can lead to a loss of braking performance and potentially cause an accident. Brake fluids with corrosion inhibition properties can help to extend the lifespan of the brakes and reduce the risk of failure, which makes them a safer and more reliable choice for your vehicle.
Property 4: Sealing Ability
Sealing ability is another important property of brake fluid that affects its performance and lifespan. Brake fluids with sealing ability are designed to seal the brake system components and prevent moisture and air from entering the system. Sealing ability is particularly important in areas where the brake system is exposed to moisture, salt, or other corrosive substances.
Brake fluids with sealing ability typically contain additives such as seal conditioners and seal lubricants. These additives help to seal the brake system components and prevent moisture and air from entering the system, which can extend the lifespan of the brakes and reduce the risk of failure.
Why is Sealing Ability Important?
Sealing ability is important because it helps to prevent moisture and air from entering the brake system. Moisture and air can cause the brakes to become less effective, which can lead to a loss of braking performance and potentially cause an accident. Brake fluids with sealing ability can help to prevent moisture and air from entering the system, which makes them a safer and more reliable choice for your vehicle.
Property 5: Compatibility
Compatibility is another important property of brake fluid that affects its performance and lifespan. Brake fluids with compatibility properties are designed to work with the specific brake system components and materials used in your vehicle. Compatibility is particularly important in areas where the brake system is exposed to different materials and substances.
Brake fluids with compatibility properties typically contain additives such as lubricants and corrosion inhibitors. These additives help to ensure that the brake fluid works effectively with the brake system components and materials, which can extend the lifespan of the brakes and reduce the risk of failure.

Why is Compatibility Important?
Compatibility is important because it helps to ensure that the brake fluid works effectively with the brake system components and materials used in your vehicle. Brake fluids that are not compatible with the brake system components and materials can cause the brakes to become less effective, which can lead to a loss of braking performance and potentially cause an accident. Brake fluids with compatibility properties can help to ensure that the brakes work effectively and safely, which makes them a safer and more reliable choice for your vehicle.
Property 6: Shelf Life
Shelf life is another important property of brake fluid that affects its performance and lifespan. Brake fluids with a longer shelf life are less likely to degrade over time, which can reduce their performance and lifespan. Shelf life is particularly important in areas where the brake fluid is stored for extended periods of time.
Brake fluids with a longer shelf life typically contain additives such as antioxidants and UV stabilizers. These additives help to prevent the brake fluid from degrading over time, which can extend its lifespan and ensure that it continues to work effectively.
Why is Shelf Life Important?
Shelf life is important because it helps to ensure that the brake fluid remains effective and safe over time. Brake fluids that degrade over time can become less effective, which can lead to a loss of braking performance and potentially cause an accident. Brake fluids with a longer shelf life can help to ensure that the brakes work effectively and safely, which makes them a safer and more reliable choice for your vehicle.
