Nowadays, cars are one of the most popular and familiar things around the world. Although this type of vehicle brings a lot of convenience to traveling, there are still many problems that occur.
One of them is that the piston caliper brake does not return to the position to perform the next cycle. From there, it creates a lot of difficulties and dangers for users.
To better understand the cause of this condition, let’s go to the following article.
The Brake Caliper Piston Won’t Go Back In: 4 Popular Reason
In general, we can see many reasons why your caliper piston brake cannot return to its original position. In other words, it cannot function as it should.
This section will help you learn about 4 primary causes of the above phenomenon that you must know to apply to your car.
First, we must mention that the piston’s ejection process has an error while performing the task.
Although, the structure of the piston brake includes many details such as Front caliper, rear caliper, transmission tool, … But the cause of the phenomenon of not returning to the old position is the rear caliper. Typically, there is a problem with the reverse rotator in the rear brake caliper.

Because the rear caliper performs the essential propulsion task, the piston must combine with the push by the counterwind rotator. Since then, it has had to do a lot of complicated work simultaneously, so the rate of deviation from the original trajectory is prevalent for this part.
For the above cause, you can completely fix it in many different ways. Depending on the tool structure you use, we will take appropriate repair measures.
In addition, to minimize the above cause, you should regularly maintain the vehicle’s transmission to fix it in time.
Caliper clamp pin
Next, we will come to the second cause of brake failure and the quick caliper clamp.
Almost all cars today apply linked brake caliper technology, so the rate of this cause is relatively high.
To allow the piston to slide accurately and smoothly, manufacturers often use brake calipers and spur bushings (caliper pins).
Due to the repeated pushing process, the caliper pin becomes thin, or in other words, corrosion occurs. In addition, the Caliper bushing may also fail and cause all operations.

To avoid this, check the clamping pin seals more often. If you see any displacement or deformation, replace the caliper pin immediately to prevent further corrosion.
In general, the leading cause lies in the Caliper clamp pin. Therefore, check this part regularly and replace it with a new one if you find any abnormalities.
In addition to the above, one of the common causes that you cannot ignore anymore is the sticking of the Piston caliper.
Because this part is almost the main thing of the entire system, if the Piston caliper stops, of course, its brakes will not be able to return.
Some of the phenomena when the above causes occur that you can refer to are as follows:
- The movement is suddenly heavier than usual
- Smoke appears when you step on the brake
- Produces a burning smell when you brake the car; the wheel temperature is also hotter and attracts brake dust.
- The car temperature gauge goes up and down while driving shows that the engine temperature is rising.
To fix this problem, you can open the brake hose to check if the piston is stuck or not? If you see an abnormality with the piston, you should not move the vehicle. Look for a quick fix and fix.
Because this detail is significant, don’t forget to take your car for regular piston maintenance to avoid unnecessary problems.
Oil in the brake hose
Finally, the cause comes from the brake hose. To overcome faulty brake hoses, you can replace the new gasket and significantly change the new oil for the brake.
Poor brake fluid is a common cause of piston retraction, from which the caliper stops working. Because oil often does the job of lubrication and cooling. So this fluid is essential to the operation of the caliper.
To prevent the brake caliper from returning, you should pay more attention to the lubricating oil. Many people have not changed the brake fluid for the car, so it has led to piston jam, internal corrosion, abnormal heating, causing severe consequences.
Note, you need to change the brake fluid every 3 years so that the hydraulic system does not have problems. In addition, choosing the right oil for the car is also a significant factor.
Now, you can ultimately determine the cause of your car’s caliper piston brake not working by checking each of the mentioned parts.
In addition to the above knowledge, we also realize that many questions have not been explicitly answered. So, in the section below, we will reply to you with more relevant questions.
What is the effect of the quick clamp piston not working?
Overall, Piston calipers not turning creates a lot of problems for your car. From there, the car’s engine will weaken and stop working. More dangerous is not ensuring traffic safety when you drive on the road. Unfortunately, if your vehicle stops suddenly on the road or can’t control them, it will easily cause an accident affecting everyone.
Can I fix the Piston caliper not returning?
As we mentioned above, you can completely repair and fix the caliper piston brake back to its original working state. Before doing so, you need to determine the cause of the front brake obstruction so that you can choose for yourself the most necessary solutions.
Can I replace the non-return caliper piston?
In addition to repairing the parts that make up the Piston caliper, you can also replace the region entirely.
However, the package replacement will cost you more. But on the contrary, it will bring you a more quality system at present. If you have good financial condition, replacing the caliper piston brake is a good and valuable job.
In short, the non-returning piston caliper brake is a big problem stemming from quite a few causes. Therefore, you need to pay attention to your car and maintain it regularly to limit this problem from happening.
We hope you will learn more about what causes piston caliper brakes to not work through this article. From there, you can make the best choices for yourself.
