Brake fluid is a critical component of a vehicle’s braking system, responsible for transmitting pressure from the brake pedal to the brake pads or shoes, which ultimately slows or stops the vehicle. The choice of brake fluid is crucial, as it affects the performance, safety, and longevity of the braking system. Among various options, water is often considered a viable alternative due to its abundance and low cost. However, water is not a suitable brake fluid, and in this blog post, we will explore the reasons behind this assertion.
The importance of brake fluid cannot be overstated. It plays a vital role in ensuring the safe operation of a vehicle, particularly in emergency situations where quick stopping is required. Brake fluid is designed to withstand high temperatures, pressures, and chemical reactions, making it an essential component of the braking system.
Water, on the other hand, is a common substance found in nature, making up approximately 71% of the Earth’s surface. While it is essential for human survival and various industrial processes, it is not suitable for use as brake fluid. In this blog post, we will delve into the reasons why water is not a suitable brake fluid, exploring its properties, limitations, and potential consequences of using it in the braking system.

Properties of Water
Water is a polar molecule, consisting of two hydrogen atoms bonded to a single oxygen atom. This unique structure gives water its characteristic properties, including high surface tension, solubility, and boiling point. While these properties make water useful for various applications, they also render it unsuitable for use as brake fluid.
High Boiling Point
Water has a high boiling point of 212°F (100°C), which makes it difficult to vaporize and evaporate quickly. In the braking system, brake fluid is subjected to high temperatures, particularly during repeated braking or in hot weather conditions. Water’s high boiling point would cause it to boil and vaporize, leading to a loss of braking performance and potentially causing damage to the braking system.
Low Viscosity
Water has a low viscosity, making it difficult to maintain a consistent flow rate in the braking system. Brake fluid, on the other hand, is designed to maintain a consistent viscosity across a wide range of temperatures, ensuring smooth and reliable braking performance. Water’s low viscosity would cause it to flow too quickly, leading to a loss of braking performance and potentially causing damage to the braking system.

Corrosive Properties
Water is a corrosive substance, capable of damaging metal components and causing rust and corrosion. In the braking system, water would react with metal components, such as brake rotors and calipers, causing damage and reducing the lifespan of these components.
Limitations of Water
Water has several limitations that make it unsuitable for use as brake fluid. Some of these limitations include:
- Lack of lubricity: Water does not provide the necessary lubricity to prevent corrosion and wear on metal components.
- Low heat capacity: Water has a low heat capacity, making it unable to absorb and dissipate heat effectively.
- High freezing point: Water has a high freezing point of 32°F (0°C), which would cause it to freeze and become brittle in cold weather conditions.
- High evaporation rate: Water has a high evaporation rate, which would cause it to evaporate quickly and lead to a loss of braking performance.
Consequences of Using Water as Brake Fluid
The consequences of using water as brake fluid are severe and potentially catastrophic. Some of these consequences include:
- Reduced braking performance: Water’s low viscosity and high evaporation rate would cause it to lose braking performance quickly.
- Damage to braking system components: Water’s corrosive properties would cause damage to metal components, such as brake rotors and calipers.
- Increased risk of accidents: Reduced braking performance and damage to braking system components would increase the risk of accidents and injuries.
- Costly repairs: Damage to braking system components would require costly repairs, potentially exceeding the cost of a new vehicle.
Alternatives to Water
Fortunately, there are several alternatives to water that can be used as brake fluid. Some of these alternatives include: (See Also: Brake Judder When Braking? The Fix Revealed)
- DOT 3 brake fluid: A type of brake fluid that meets the requirements of the Society of Automotive Engineers (SAE) and is widely used in the automotive industry.
- DOT 4 brake fluid: A type of brake fluid that meets the requirements of the SAE and is designed for use in high-performance vehicles.
- DOT 5 brake fluid: A type of brake fluid that meets the requirements of the SAE and is designed for use in vehicles with advanced braking systems.
Recap
In conclusion, water is not a suitable brake fluid due to its properties, limitations, and potential consequences of using it in the braking system. The high boiling point, low viscosity, and corrosive properties of water make it unsuitable for use as brake fluid. Instead, there are several alternatives available, including DOT 3, DOT 4, and DOT 5 brake fluids. It is essential to use the correct type of brake fluid to ensure safe and reliable braking performance.
