The importance of maintaining the proper fluid levels and types in your vehicle cannot be overstated. Two of the most critical systems in your car are the braking and power steering systems, which rely on specific fluids to function properly. Brake fluid is designed to handle the high-pressure demands of the braking system, while power steering fluid is formulated to lubricate and cool the power steering pump and components. But can you use brake fluid for power steering? The answer is not a simple yes or no, and it’s essential to understand the differences between the two fluids before making any decisions.

What is Brake Fluid?
Brake fluid is a hydraulic fluid designed to transmit pressure from the brake pedal to the brake calipers, causing the brake pads to clamp onto the rotor and slow or stop the vehicle. Brake fluid is a glycol-based or silicone-based fluid that is designed to withstand the high pressures and temperatures generated by the braking system. It is also formulated to be non-corrosive and non-conductive, making it safe for use in the braking system.
Types of Brake Fluid
There are several types of brake fluid available, including:
- DOT 3: A glycol-based fluid that is suitable for most passenger vehicles.
- DOT 4: A glycol-based fluid that is designed for high-performance vehicles and provides better boiling point protection.
- DOT 5: A silicone-based fluid that is designed for use in vehicles with ABS systems.
- DOT 5.1: A silicone-based fluid that is designed for use in vehicles with ABS systems and provides better lubricity.
What is Power Steering Fluid?
Power steering fluid is a hydraulic fluid designed to lubricate and cool the power steering pump and components. It is typically a glycol-based or silicone-based fluid that is formulated to provide better lubricity and corrosion protection than brake fluid. Power steering fluid is designed to withstand the high pressures and temperatures generated by the power steering system, and it is also formulated to be non-corrosive and non-conductive.
Types of Power Steering Fluid
There are several types of power steering fluid available, including:
- Conventional power steering fluid: A glycol-based fluid that is suitable for most passenger vehicles.
- Synthetic power steering fluid: A synthetic-based fluid that provides better lubricity and corrosion protection than conventional power steering fluid.
- Full synthetic power steering fluid: A fully synthetic fluid that provides the best lubricity and corrosion protection available.
Can You Use Brake Fluid for Power Steering?
The short answer is no, you should not use brake fluid for power steering. While both fluids are hydraulic fluids, they are designed for different purposes and have different formulations. Brake fluid is designed to withstand the high pressures and temperatures generated by the braking system, while power steering fluid is designed to provide better lubricity and corrosion protection for the power steering system.

Risks of Using Brake Fluid for Power Steering
Using brake fluid for power steering can pose several risks, including:
- Corrosion: Brake fluid can corrode the power steering components, leading to premature wear and failure.
- Lack of lubricity: Brake fluid is not designed to provide the same level of lubricity as power steering fluid, which can lead to increased wear and tear on the power steering components.
- Increased pressure: Brake fluid is designed to withstand the high pressures generated by the braking system, but it may not be able to handle the lower pressures generated by the power steering system, which can lead to reduced performance and efficiency.
Why Shouldn’t You Use Brake Fluid for Power Steering?
There are several reasons why you should not use brake fluid for power steering, including:
1. Different Formulations: Brake fluid and power steering fluid have different formulations that are designed for specific purposes. Brake fluid is designed to withstand the high pressures and temperatures generated by the braking system, while power steering fluid is designed to provide better lubricity and corrosion protection for the power steering system.
2. Corrosion Protection: Brake fluid is not designed to provide the same level of corrosion protection as power steering fluid, which can lead to premature wear and failure of the power steering components.
3. Lubricity: Brake fluid is not designed to provide the same level of lubricity as power steering fluid, which can lead to increased wear and tear on the power steering components. (See Also: Brake Checking Is Illegal? The Consequences)
4. Pressure Handling: Brake fluid is designed to withstand the high pressures generated by the braking system, but it may not be able to handle the lower pressures generated by the power steering system, which can lead to reduced performance and efficiency.
Recap and Conclusion
In conclusion, using brake fluid for power steering is not recommended due to the different formulations, corrosion protection, lubricity, and pressure handling capabilities of the two fluids. It is essential to use the correct type of fluid for your vehicle’s power steering system to ensure proper performance, efficiency, and longevity. Always consult your vehicle’s owner’s manual or a trusted mechanic if you have any questions or concerns about the type of fluid to use in your vehicle’s power steering system.
Frequently Asked Questions
Q: Can I use DOT 5 brake fluid for power steering?
A: No, DOT 5 brake fluid is not suitable for use in power steering systems. It is designed for use in ABS systems and is not formulated to provide the same level of lubricity and corrosion protection as power steering fluid.
Q: Can I use synthetic power steering fluid in my vehicle’s braking system?
A: No, synthetic power steering fluid is not suitable for use in braking systems. It is designed to provide better lubricity and corrosion protection in power steering systems and may not provide the same level of performance and protection in braking systems.
Q: Can I mix brake fluid and power steering fluid?
A: No, it is not recommended to mix brake fluid and power steering fluid. Each fluid is designed for specific purposes and has different formulations that are not compatible with each other. (See Also: Do You Have To Turn Rotors When Changing Brake Pads? The Ultimate Guide)
Q: What happens if I accidentally use brake fluid in my power steering system?
A: If you accidentally use brake fluid in your power steering system, it is essential to flush the system and replace the fluid with the correct type of power steering fluid as soon as possible. Failure to do so can lead to premature wear and failure of the power steering components.
Q: Can I use DOT 3 brake fluid in my power steering system?
A: No, DOT 3 brake fluid is not suitable for use in power steering systems. It is designed for use in passenger vehicles and is not formulated to provide the same level of lubricity and corrosion protection as power steering fluid.
