Your car’s power steering system is a crucial component that makes maneuvering your vehicle a breeze, especially at low speeds and when turning. It provides the necessary hydraulic assistance to turn the steering wheel with ease. Similarly, your brake system relies on hydraulic pressure to bring your car to a safe stop. While both systems utilize hydraulic fluid, using the wrong type can lead to catastrophic consequences. So, the question arises: can you use brake fluid as power steering fluid? The answer is a resounding no. This blog post will delve into the reasons why mixing these fluids is a dangerous mistake and explore the potential damage it can cause to your vehicle.

Why Brake Fluid and Power Steering Fluid Are Different
Though both brake fluid and power steering fluid are hydraulic fluids, they have distinct chemical compositions and properties tailored to their specific functions. Brake fluid is designed to withstand extremely high temperatures generated during braking and to resist corrosion in the brake system’s metal components. Power steering fluid, on the other hand, needs to lubricate the power steering pump and rack, and it must be compatible with seals and hoses within the power steering system. Using the wrong fluid can compromise the performance and longevity of both systems.
Chemical Composition
Brake fluid typically contains glycol ethers or a similar compound that has a high boiling point and excellent thermal stability. This is crucial because brake fluid experiences extreme heat during repeated braking. Power steering fluid, on the other hand, often contains additives that enhance lubricity and prevent foaming, which can occur under pressure in the power steering system. These additives are not present in brake fluid and can lead to damage in the power steering system.
Viscosity
Viscosity refers to a fluid’s resistance to flow. Brake fluid has a higher viscosity than power steering fluid. This higher viscosity is necessary for brake systems to transmit hydraulic pressure effectively. Using brake fluid in the power steering system can result in increased friction and resistance, making steering difficult and potentially damaging the power steering pump.
Corrosion Resistance
Brake fluid is formulated to resist corrosion in the harsh environment of the brake system. Power steering fluid also needs corrosion resistance, but it may not be as critical as in the brake system. Using brake fluid in the power steering system can potentially lead to corrosion in components not designed to withstand its specific chemical composition.
Potential Damage from Using Brake Fluid in Power Steering
Mixing brake fluid and power steering fluid can have severe consequences for your vehicle’s power steering system. The following are some potential problems you may encounter:
Power Steering Pump Failure
The power steering pump is responsible for generating the hydraulic pressure that assists in steering. Using brake fluid, which is too viscous, can put excessive strain on the pump, leading to overheating, wear, and eventual failure. A failed power steering pump will result in a loss of power steering assistance, making it extremely difficult to steer your vehicle. (See Also: How to Brake Properly? For Safer Driving)
Sealing Issues
Power steering systems rely on seals to prevent leaks and maintain hydraulic pressure. Brake fluid can attack and damage these seals, causing them to leak. Leaks in the power steering system can lead to a loss of fluid, reduced steering assistance, and potential damage to other components.
Hose Degradation
The hoses that carry power steering fluid are made of specific materials that are compatible with the fluid’s chemical composition. Brake fluid can degrade these hoses, making them brittle and prone to leaks or bursting. A burst hose can result in a sudden loss of power steering and a dangerous situation.
Steering Rack Damage
The steering rack is a critical component that translates the steering wheel’s movement into actual steering action. Brake fluid can damage the seals and components within the steering rack, leading to premature wear and potential failure. A damaged steering rack can result in uneven steering, loss of control, and difficulty maneuvering your vehicle.
Importance of Using the Correct Fluid
Using the correct fluid for your vehicle’s systems is paramount for maintaining optimal performance, safety, and longevity. Always refer to your owner’s manual to determine the specific type of fluid recommended for your power steering system. Never mix fluids or use a fluid that is not explicitly approved for your vehicle.
Consequences of Using the Wrong Fluid
Using the wrong fluid can lead to a range of problems, from minor performance issues to catastrophic failures. These problems can not only damage your vehicle but also pose a safety risk to you and others on the road.
Importance of Regular Fluid Checks and Changes
Regularly checking and changing your power steering fluid is essential for maintaining its performance and preventing potential damage. Refer to your owner’s manual for the recommended intervals for fluid checks and changes. If you notice any leaks, discoloration, or changes in the fluid’s consistency, have your power steering system inspected by a qualified mechanic immediately.

Can I Use Brake Fluid as Power Steering Fluid?
Why Mixing Brake Fluid and Power Steering Fluid Is a Bad Idea
Mixing brake fluid and power steering fluid is a recipe for disaster. These fluids have different chemical compositions, viscosities, and properties that are specifically designed for their respective systems. Using brake fluid in your power steering system can lead to a cascade of problems, including pump failure, sealing issues, hose degradation, and steering rack damage.
The Bottom Line
Never use brake fluid as power steering fluid. Always use the fluid that is specifically recommended for your vehicle’s power steering system. By following this simple rule, you can help ensure the proper functioning and longevity of your vehicle’s power steering system and avoid potentially dangerous situations on the road.
FAQs
Can I top off my power steering fluid with brake fluid?
No, you should never top off your power steering fluid with brake fluid. Doing so can damage your power steering system and lead to costly repairs.
What happens if I accidentally mix brake fluid and power steering fluid?
If you accidentally mix brake fluid and power steering fluid, it’s important to have your power steering system flushed and refilled with the correct fluid as soon as possible. The mixture can damage seals, hoses, and other components.
How can I tell if my power steering fluid is the wrong type?
If you’re unsure about the type of power steering fluid in your vehicle, consult your owner’s manual or a qualified mechanic. The fluid should be a clear or slightly amber color. If it is dark, discolored, or has a burnt smell, it may be contaminated and needs to be changed. (See Also: How to Paint Brake Calipers with a Brush? Get Perfect Results)
Is it safe to drive with mixed brake fluid and power steering fluid?
It is not safe to drive with mixed brake fluid and power steering fluid. The mixture can cause your power steering to fail, making it difficult or impossible to steer your vehicle.
Where can I find the correct power steering fluid for my vehicle?
You can find the correct power steering fluid at most auto parts stores. Be sure to specify your vehicle’s make, model, and year to ensure you get the right fluid.
In conclusion, using brake fluid as power steering fluid is a dangerous practice that can lead to severe damage and safety risks. It is crucial to understand the differences between these fluids and to always use the fluid specifically recommended for your vehicle’s power steering system. Regular fluid checks and changes are essential for maintaining the health and longevity of your power steering system. By following these guidelines, you can ensure that your vehicle’s steering system operates smoothly and safely.
