[Serious misunderstanding] Increase the air flow of the main valve or relay valve, and the braking effect will be improved
Regarding the problem of truck braking, most drivers will be deceived, many roadside shops for the sake of profit, replace some of the original brake valve parts, in fact, the overflow of the master cylinder or relay valve is increased, giving people a feeling of increased braking power.
● What is the principle and why do you feel that the braking is strong
In fact, it only ignores the part of the stroke with small braking air volume and directly enters the atmospheric volume stroke. Taking the area with a large braking force as a premise, the foot feels a little braking and it comes, giving people the feeling that the brakes have improved.

Initially, the master cylinder piston was polished or the gasket was added to achieve the above effect, which should be the earliest form, and the changed master cylinder is actually the same reason, now it is just a complete product of mass production, and it can be replaced directly.
● Replacing the modified valve is actually not reliable
In fact, these modified valves on the market shorten the response time by increasing the amount of air overflow, which is actually just the subjective consciousness of the owner that the brakes have become stronger.
Some car owners even modify the new car when they go home, and some car owners replace the pump valve of the original car with modified valves after a certain mileage of the vehicle due to wear and tear of brake components or improper maintenance. Brakes are not unilateral, but a whole, and coordination must be paid attention to, especially trailers.
Replace the brake valve
We all know that the brakes of the trailer and the main car can be coordinated with each other to ensure the effect of braking. After replacing the modified valves, the coordination of the vehicle's brakes was destroyed.

And after the modification, the linear growth of braking force almost disappeared, and there was a phenomenon that some car owners said that if you step lightly, you will lock to death, and if you step on it heavily, it will be useless. Due to the increased amount of air in the modified shipment, the brake pressure will also drop faster, and for some cars with slower inflation, the downhill air pressure may be insufficient, which is also a more dangerous and troublesome thing. Many car owners may have had such an experience, after modifying the valves, the brake drum is obviously not durable.
Brake drums often crack, and sometimes the new brake drum that has just been replaced has to be replaced before it has run much mileage. At the same time, the braking distance of the vehicle is not shortened, but lengthened, and it is unreliable to blindly modify without finding the reason for the deterioration of the brakes.
● Good brakes Maintenance is very important
In practice, brakes are not easy to use, and many of them are caused by incorrect maintenance. For example, the use of counterfeit brake pads and brake drums, and some may neglect the maintenance of the brake air circuit, such as replacing the drying tank from time to time; The brakes are only replaced with brake pads, and the camshaft and other components are not maintained, which are factors that affect the braking effect and stability.
The brake problem should be solved from the root problem
If you don't fundamentally find out the problem of brake deterioration, and modify the valves, you will feel that the brakes are good again in the short term, and after a period of time, these problems will slowly amplify, so that your brakes fall into a vicious repair cycle, no matter what you replace, it doesn't seem to work, so the usual correct maintenance is the right posture.
To sum up: the quality of the brakes is directly related to the driving safety of the car owner, and the modified valves are ostensibly enhanced to ensure safety. The quality of the brake is more about the usual maintenance, and it is unreliable to simply change the valve to solve the problem.
Focus on the research and development of automotive brake systems and pneumatic brake valves to promote the development of the auto parts industry!
