The importance of understanding the differences between brake fluid and power steering fluid cannot be overstated. As a car owner, it’s crucial to know what type of fluid is used in your vehicle and how to maintain it properly. Brake fluid and power steering fluid are two distinct types of fluids that serve different purposes in your vehicle. While they may seem similar, they are not interchangeable, and using the wrong fluid can lead to serious consequences, including damage to your vehicle’s components and even accidents.

What is Brake Fluid?
Brake fluid is a type of hydraulic fluid used in brake systems to transmit pressure from the brake pedal to the brake calipers. It’s designed to withstand high temperatures and pressures, and its primary function is to provide a smooth and consistent braking experience. Brake fluid is typically a mixture of glycols, such as ethylene glycol or propylene glycol, and other additives that enhance its performance and durability.
Types of Brake Fluid
There are several types of brake fluid, including:
- DOT 3: This is the most common type of brake fluid and is suitable for most passenger vehicles.
- DOT 4: This type of brake fluid is designed for high-performance vehicles and provides better boiling point and corrosion protection.
- DOT 5: This type of brake fluid is silicone-based and is used in vehicles that require a non-absorbing brake fluid.
What is Power Steering Fluid?
Power steering fluid is a type of hydraulic fluid used in power steering systems to transmit pressure from the steering wheel to the steering gear. Its primary function is to provide a smooth and effortless steering experience. Power steering fluid is typically a mixture of mineral oil, synthetic oil, or a combination of both, and may contain additives to enhance its performance and durability.
Types of Power Steering Fluid
There are several types of power steering fluid, including:
- Mineral-based: This type of fluid is made from petroleum-based products and is suitable for most passenger vehicles.
- Synthetic-based: This type of fluid is made from synthetic materials and provides better performance and durability in extreme temperatures.
- Hybrid-based: This type of fluid is a combination of mineral-based and synthetic-based fluids and provides a balance of performance and cost.
Why Can’t You Use Brake Fluid in Power Steering?
Using brake fluid in power steering can be dangerous and may cause serious damage to your vehicle’s components. Here are some reasons why:
Corrosion: Brake fluid is designed to withstand high temperatures and pressures, but it can corrode the metal components in the power steering system, leading to premature wear and tear. (See Also: What Is A Lip On Brake Disc? Explained)
Viscosity: Brake fluid has a higher viscosity than power steering fluid, which can cause the power steering pump to work harder and increase the risk of overheating.
Boiling Point: Brake fluid has a lower boiling point than power steering fluid, which can cause it to vaporize and lose its lubricating properties, leading to premature wear and tear on the power steering components.
Why Can’t You Use Power Steering Fluid in Brakes?
Using power steering fluid in brakes can also be dangerous and may cause serious damage to your vehicle’s components. Here are some reasons why:
Lack of Corrosion Protection: Power steering fluid is not designed to provide the same level of corrosion protection as brake fluid, which can lead to premature wear and tear on the brake components.
Inadequate Lubrication: Power steering fluid is designed to provide lubrication for the power steering components, but it may not provide the same level of lubrication for the brake components, leading to premature wear and tear.

Boiling Point: Power steering fluid has a higher boiling point than brake fluid, which can cause it to vaporize and lose its lubricating properties, leading to premature wear and tear on the brake components.
Conclusion
In conclusion, brake fluid and power steering fluid are two distinct types of fluids that serve different purposes in your vehicle. While they may seem similar, they are not interchangeable, and using the wrong fluid can lead to serious consequences. It’s essential to use the correct type of fluid for your vehicle’s brake and power steering systems to ensure optimal performance and longevity.
Recap
Here’s a recap of the key points:
- Brake fluid is used in brake systems to transmit pressure from the brake pedal to the brake calipers.
- Power steering fluid is used in power steering systems to transmit pressure from the steering wheel to the steering gear.
- Brake fluid and power steering fluid are not interchangeable and should not be used in each other’s systems.
- Using the wrong fluid can cause serious damage to your vehicle’s components and even accidents.
