How to Fix Power Steering Fluid in Brake System

If your car has power steering fluid in the brake system, you need to know how to fix it. This blog post will teach you how to fix the problem and prevent it from happening again.

How To Fix Power Steering Fluid In Brake System

We’ll discuss what power steering fluid is and why it has a tendency to find its way into the brake system. We’ll also offer advice on how to stop this problem before it starts by taking preventative measures.

What Is Power Steering Fluid in Brake System?

Power steering fluid is a type of oil that is used to lubricate the hydraulic system that moves your vehicle’s front wheels. This type of brake needs this kind of oil because it uses an engine-driven pump, not manually pushing or pulling on a lever. Power steering fluid also needs to be thick enough to stop leaks and be stable at high temperatures.

What Causes Power Steering Fluid Leaks?

Power steering fluid leaks can be caused by:

  • Corrosion in the power steering pump. If it is not changed, this leads to a leak and eventually to the failure of the entire system.
  • Leaking seals on the hose that attaches between the pump and pressure regulator as well as at other places along these lines. These hoses are made out of rubber or plastic and are prone to wear while you drive over time since they rub against each other when moving around corners too much.
  • This creates friction which heats up with use, so if one side starts leaking first, it will quickly become red hot from rubbing against itself all day long under high pressure, leading to more frays until enough heat builds up for it to finally combust and makes a hole.
What Causes Power Steering Fluid Leaks
  • When the power steering fluid reaches too high of heat, it can become thick like syrup or gel instead of staying at its normal liquid state, which causes slippage between internal parts that rely on lubrication for smooth operation. This leads to an increase in friction as well as some corrosion.
  • You’ll notice your vehicle starting to jerk back and forth or have a stiff feeling when you turn the wheel. If this is happening to your car, it’s most likely time for a power steering fluid change!

Steps on How to Fix Power Steering Fluid in Brake System

Step One: Find the power steering fluid reservoir and top off, if needed.

Step Two: Locate the brake master cylinder reservoir filled with DOT or silicone brake fluid (not power steering fluid).

Step Three: Check the fluid level. If there is too much, top-up to a maximum of MAX mark on dipstick; if not enough, add only until MIN mark is reached.

Step Four: Add brake fluid through the bleeder valve at the right front wheel or left rear wheel until pressure builds up and air bubbles appear (top off as needed). Repeat this step for other wheels in sequence, starting from the opposite side of the car.

Step Five: Turn on your car’s engine so that there is a demand for coolant in the radiator. Alternatively, you can turn it off, but this will be more difficult to diagnose what happened later.

Step Six: Take out any air from the system by pumping up brakes repeatedly until they feel firm. This may take two minutes of continuous pumping; use your best judgment about whether enough pressure has been established. Be careful not to overpressurize! Do not pump handle more than 25 times total!

Step Seven: Release the handbrake slowly while pressing down on the accelerator to increase pressure on brake fluid.

Step Eight: If it’s not leaking, you’re done! Replace any air in a system with brake fluid and top off the reservoir if needed. Wipe excess oil from the reservoir cap seal with a paper towel and replace it after topping off power steering fluid levels.

Some Tips & Advice To Prevent Power Steering Fluid Leakage:

Tip 1: Replace hose clamps every year.

Tip 2: Inspect hoses annually for leakage, bulges, or cracks.

Tip 3: Check the power steering fluid level regularly and add as needed to keep it at recommended levels.

Tip 4: If the power steering fluid is low, pour in some of a similar type.

Tip 5: Verify that any leaks are from hoses or seals and not from under the vehicle.

Tip 6: Tighten loose connections to prevent leakage around fittings.

Tip 7: Replace leaking parts as necessary with new ones made for your car’s make and model; consult an expert on what parts you need before ordering them.

Tip 8: If you notice a leak, locate the source of the leak by checking under your vehicle’s hood and tracing back to where it is coming from on the engine side of things or on the passenger side!

Frequently Asked Questions

How Often Should You Change Power Steering Fluid?

The frequency of your vehicle’s oil changes may vary. Always consult your owner’s manual for specific instructions. For example, some vehicles may require an oil change as often as every 30,000 miles, while others may only need it once a year or less.

What Is The Difference Between Power steering And Brakes?

If you have power brakes and are experiencing problems with them (such as hard brake pedal), then there may be an issue with the power booster unit that will need to be addressed by a certified mechanic before continuing driving. On the other hand, if you have power steering and are noticing issues such as reduced turning radius when accelerating or the steering wheel locking up, then you need to have the fluid checked and possibly changed.


If you have power steering fluid in your brake system, it means that the seals are damaged or broken. You need to fix this as soon as possible, because if you don’t, the leak can cause major damage to other parts of your car.

The best way to get this taken care of is by bringing it into a professional mechanic’s shop, where they should diagnose and repair the issue promptly. You’ll want them to check any leaks with an oil dry test first so that they know what caused this problem before making repairs.
