Essential Information
- Power steering fluid is typically red or green in color and has a lower boiling point than brake fluid.
- Brake fluid is designed for use in braking systems, while power steering fluid is used in power steering systems.
- Using brake fluid in power steering systems can lead to serious consequences, including damage to the steering system, reduced steering ability, and potential safety hazards.
Brake fluid and power steering fluid are essential liquids in a vehicle, but they are not interchangeable. Many vehicle owners mistakenly believe that brake fluid can be used as power steering fluid, leading to potentially dangerous consequences. This blog post aims to clarify the differences between these two fluids and emphasize why they should not be substituted for each other.
Understanding Brake Fluid
Brake fluid is a hydraulic fluid specifically designed for use in brake systems. Its primary function is to transfer force from the master cylinder to the brake calipers or wheel cylinders, enabling the actuation of the brakes. Brake fluid is typically amber or clear in color and has a high boiling point to withstand the heat generated by the braking process.
Understanding Power Steering Fluid
Power steering fluid is a hydraulic fluid used in power steering systems. It assists the driver in steering the vehicle by reducing the effort required to turn the steering wheel. Power steering fluid is typically red or green in color and has a lower boiling point than brake fluid.
Key Differences between Brake Fluid and Power Steering Fluid
1. Composition: Brake fluid is typically made from glycol ethers, while power steering fluid is composed of mineral oils or synthetic fluids.
2. Function: Brake fluid is designed for use in braking systems, while power steering fluid is used in power steering systems.
3. Viscosity: Brake fluid has a higher viscosity than power steering fluid, meaning it flows less easily.
4. Boiling Point: Brake fluid has a higher boiling point than power steering fluid, making it more resistant to heat.
5. Color: Brake fluid is typically amber or clear, while power steering fluid is typically red or green.
Consequences of Using Brake Fluid in Power Steering
Substituting brake fluid for power steering fluid can have severe consequences for your vehicle’s steering system:
- Seal Damage: Brake fluid can damage the seals in the power steering system, leading to leaks and reduced steering performance.
- Corrosion: Brake fluid can corrode the metal components in the power steering system, causing premature failure.
- Reduced Steering Ability: Damaged seals and corrosion can result in reduced steering ability, making it difficult to control the vehicle.
- Pump Failure: In extreme cases, brake fluid can cause the power steering pump to fail, resulting in complete loss of steering control.
Conclusion
Brake fluid and power steering fluid are not interchangeable fluids. Using brake fluid in power steering systems can lead to serious consequences, including damage to the steering system, reduced steering ability, and potential safety hazards. Always refer to your vehicle’s owner’s manual for the correct type of fluid to use in each system.
FAQ
1. Can I mix brake fluid and power steering fluid?
No, mixing brake fluid and power steering fluid is not recommended. It can damage the seals and components in both systems.
2. What happens if I accidentally put brake fluid in my power steering system?
Flush the system with the correct power steering fluid as soon as possible to mitigate potential damage.
3. How often should I change my brake fluid?
Brake fluid should be flushed and replaced every 2-3 years or as recommended in your vehicle’s owner’s manual.
4. How often should I change my power steering fluid?
Power steering fluid should be flushed and replaced every 3-5 years or as recommended in your vehicle’s owner’s manual.
5. Can I use universal fluid in my brake and power steering systems?
Universal fluids are not recommended for use in either brake or power steering systems. Always use the specific fluid type recommended for each system.
