Does Brake Fluid Stop Power Steering Leak?

This post contains affiliate links. Read the full disclosure here.

It is widely known that brake fluid can cause damage to the power steering of your vehicle. And this commonly happens if you mistakenly put this fluid into your power steering system, which implies that you just have to flush it thoroughly.

Technically speaking, you can drive with a power steering leak, but not for too long since it can become more difficult to maneuver the car, not to talk of the endeavor being a very dangerous one too.

In such an incidence, your best response should be to get a qualified person to assess the vehicle as soon as it is possible in case you may have a power steering leak.

Power steering leak is simply the loss of very vital fluid that can in extreme circumstances lead to power steering failure.

When your power steering fails, it is likely not going to be possible for you to turn the car with the needed force.

This occurrence can lead to very unsafe situations and worse, it can even lead to avoidable accidents as well.

Therefore, should you detect any power steering leak, it is not a problem you should treat with levity for what it portends; a gravely dangerous situation at best.

Your power steering leak can be caused by damaged, poorly installed, or even defective seals and gaskets in your power steering rack.

Other sources of this leak could be the junctions between the vehicle’s reservoir, lines, or even the steering rack itself, as well as the steering pump mechanism.

Diligent inspection will tell you what or where the leak is coming from. On a general note, power steering leak comes from usage and also time. As time goes by, the car ages, and consequently, its ‘O’ rings are likely to lose both form and mass.

The same thing also happens with the seals too. Because the components are not able to work satisfactorily, then, your power steering fluid may begin to leak in response.

Under certain conditions, brake fluid is commonly used with appreciable results in cases of power steering or even main rear leaks by simply adding about half a bottle of brake fluid or 4 to 6 oz. Break fluid in power steering leak works impressively.

Furthermore, brake fluid is cheaper than the conventional power steering leak stop chemical and it is also as effective in comparison too, although it is temporary.

Break fluid stops power steering leaks by making the seals swell, although this process does not give a very reliable solution to the leak, especially since, eventually, all the seals, and possibly even the hoses, may end up bursting wide open.

To this end, Blueflame power steering leak antidote may help in cases of bad seals by preventing any leakage, but, unfortunately, it may be of some harm to other important parts of the car, such as its power steering system itself.

This is because brake fluid may not necessarily be compatible with the seal materials used in the power steering system, which may necessitate the use of Bandaid to stop any leak.

In summary, brake fluid can stop power steering leaks. However, it can also damage other vital car components and eventually worsen the leak too.

Therefore, you should avoid using it for this purpose, despite everything that may stand in its favor.

What causes a power steering leak?

Power steering fluid functions as a good lubricant for the hydraulic mechanism which moves the front wheels of the vehicle.

Some particular brake systems have to have this sort of arrangement for brakes because they use engine-driven pumps, not any manual pushing or the pull on a lever.

In addition, it may also require some fluid that is thick enough to prevent any loss and make it stable even at high temperatures. It is this heat that usually causes the chemicals in the fluid to break down, such as polyolefins or plastics.

Commonly, power steering leaks are caused by corrosion in the power vehicle’s power steering pump.

Whenever the pump is changed, it may cause a leak and eventually lead to the complete failure of the whole system itself.

Secondly, power steering leaks can be caused by damaged or worn-out seals particularly the hose that attaches the pump to its pressure regulator, in addition to other places along the lines.

Commonly, these hoses are made up of either plastic or rubber, which are susceptible to wear and tear over time, especially since they persistently rub against each other when negotiating corners.

Finally, friction creates heat, and therefore, if one side starts to leak, it may quickly become so hot that it can cause frays until enough heat is generated to finally burst open and create a hole for the leak to occur. (Read Also: Can Warped Rotors Cause Vibration At High Speeds?)

Very hot power steering fluid can become as thick as a syrup or gel rather than stay at its normal liquid state. This can cause slippage between the internal parts which rely on lubrication for their efficient functions. Eventually, this leads to a sort of increase in friction as well as some corrosion too.

Ultimately, the vehicle may start to become jerky by going back and forth. In other cases, the vehicle can also have a stiff feel particularly when you are turning its wheel. Should this happen, it is indicative of the need for power steering fluid change.

How does brake fluid stop power steering leak?

Brake fluid contains certain organic constituents that may affect either rubber or plastic seals. When these seals are affected, they are likely to swell, which does not permit a power steering leak.

However, eventually, the seals can become damaged leading to persistent power steering leaks with all their attendant consequences. (Read Also:Can Brake Fluid Be Used As Penetrating Oil?)

This means that brake fluid can stop power steering leaks but only temporarily since eventually, the leak will become much worse due to the total degradation of the rubber or plastic in the seals.

What should be used in stopping power steering leaks aside from brake fluid?

Several substances are used to stop power steering leaks. Some of these chemicals are Lucas Power Steering Stop Leak. It is said to be 100 percent guaranteed to stop any leak in your power steering units. In addition, it corrects any rack and pinion problems as well.

It is said to also be effective in reducing slack, squeals, and hard spots in damaged, worn-out racks and pinions.

Furthermore, stop leaks can create a very reliable seal in numerous areas within your cooling system, although there are instances where it may not work well.

Any bad leak located between the end tanks of your radiator, a hose leak, a coolant reservoir tank, or a water pump is not likely to seal properly.

There is also the Blue Devil Power Steering Stop Leak which can permanently stop power steering leaks, especially in power steering vehicles, differentials, or even the rack and pinion steering mechanism.

It is both very safe and easy to use, aside from the fact that it works effectively on either gasoline or diesel engines too.

Is there equipment to be used in stopping power steering leaks?

The major equipment needed to stop a power steering leak is the damaged components of the system such as the seals or gaskets as well as other metallic tools that you may require to loosen bolts and nuts in the process.

In addition, you are going to need replacement power steering fluid and possibly fresh brake fluid too.

How do I stop my power steering from leaking in the future?

There are several ways through which you can stop your power steering from leaking subsequently. First, make sure that you change your power steering clamps at least once every year. Second, inspect your hoses regularly for signs of any leakage, swelling, or cracks.

Third, always inspect your power steering fluid level and top it up as required, in order not to fall short of the recommended level. Four, make sure that any leaks are either from the seals or hoses and not from beneath the vehicle.

Five, tighten any loose connections to prevent leakage around your fittings. Seven, make sure that you replace any leaking parts when necessary with new ones compatible with the model or make of your car. (Read Also: Does Brake Caliper Position Matter?)

Finally, trace all sources of leakage by inspecting beneath the vehicle from the hood to where it is coming from the on side of the engine or passenger side.

Frequently asked questions(FAQ)

How do you flush power steering fluid?

To flush your power steering, you should first pump all the old fluid out of its reservoir before you refill it with a new and clean one.

Thereafter, you should locate a low-pressure line in the power steering mechanism. These low-pressure lines will run from the steering rack or rear back up to the power steering fluid reservoir itself.

Can you use transmission fluid for brake fluid?

No, you cannot use transmission fluid as a substitute for brake fluid. In other words, transmission fluids and brake fluids are not interchangeable especially since they are made of different substances.

If you should dare to use transmission fluid as brake fluid, you are up against severe damage in the car or its braking system. Most notably, brake fluids are produced to stay very stable regardless of any severe temperature variations.
