Q & A
Question

Is ceramic fiber added to the formula a ceramic formula?

Answer

No. Ceramic fiber is only one of the commonly used fibers for brake pads, as well as metal fiber, mineral fiber, wood fiber, aramid fiber, etc. Their function is to connect various fillers, just like when adding rural mud walls. Straw is the same.

Question

What is the noise of the brake pads?

Answer

The noise is mainly the frequency resonance. If the natural frequencies of the two materials or components are the same, resonance is easy. The brake pad alone solves the noise is very simple, the service life is simple to solve alone, and it is very simple to solve the disc alone. There are many factors in the noise generation. The whole brake assembly system is the cause of noise. The improper selection of the brake disc and the serious wear of the disc will cause noise. In many cases, everyone has wronged the brake pads.

Question

I feel that the metal content is hard, and the harder is definitely more noise. Some auto repair shops say so, right?

Answer

Wrong. Many of these statements are the auto repair factory's statement and are not scientific. The main car in the US car is mainly a semi-metal formula, which contains a lot of metal. Have you heard a lot of noise? Noise is not directly related to hard and soft. The grinding disc and noise only indicate that the product formula is not mature, and has nothing to do with the metal. In fact, the metal material is mainly used to connect filler and heat conduction in the formulation. At the same time, their hardness and disc are not much different, and will not cause great wear on the disc. The real grinding disc and the increase of braking capacity are not for you. These metals, but the abrasive fillers that you can't see are harder than the brake discs, they are actually emery, and they are similar materials to your common sandpaper and grinding wheels.

Question

Why do some of the discs have a groove that has been ground? Is the brake pad very hard?

Answer

The hardness of the brake pads is standard in the country, basically between 33 and 70 Shore hardness. This hardness is not the main cause of wear on your brake discs. The grinding agent in the brake pads is the main component of the wear plate. The soft and hard brake pads are not the cause of severe wear on the disc. In addition, the unreasonable disc behavior of many auto repair shops can also cause excessive wear of the brake discs.

Question

The brake pad I bought for 70 dollars is also very good?

Answer

The braking effect is good. The braking ability of the brake pads is very simple. It is necessary to maintain the stability of the brakes under high temperature, emergency, high speed and rain. This is difficult. The original car, more demanding comfort, noise, environmental protection and other indicators, which makes the brake pads more difficult. Therefore, your simple normal driving feels good, does not mean that you have the safety performance of your original car brakes under various emergency conditions. To be honest, the original car of your private car will only be replaced by a brake pad after 4 or 5 years of operation. If you say 70 yuan as you said, do you think this profit can support the brake pad factory? Of course not, can't you do? You know.

Question

As long as there is no noise in the brake pads, can you stop the car? Is it so mysterious?

Answer

As mentioned above, it is very simple to solve the noise alone. But the main function of the brake pads is not the noise problem, but the safety. The market is now paying too much attention to noise and ignoring the main functions of the brake pads. As for everyone saying that the brake car is not enough? That's right, it's OK to stop the car, but you may not have thought about it. You can brake the car on the flat road and can brake the car at normal speed, but can you brake the car under emergency braking? Can you brake the car at the high temperature of the continuous braking of Panshan Road? Can you guarantee the braking distance at 100 km/h on rainy days? The original brake pads must be guaranteed to be stable when we need safety. At this point, I believe that many car owners who think that the car is on the road have not thought of it.

Question

What is the short life of the brake pads?

Answer

Why is the brake distance of inferior products in the case of emergency braking? A: Like all objects, the intermolecular link strength of the material structure is reduced at high temperatures. The principle of brake braking is to let the kinetic energy be converted into heat energy by friction to achieve braking (energy balance theory). Therefore, a large amount of heat generated by the friction between the brake pads and the disc will accumulate on the surface of the friction material of the brake pad, and the original brake In order to maintain sufficient strength of the brake pads under such high temperature conditions, it is necessary to use materials such as high temperature resistant resin, high purity graphite, high purity barium sulfate, etc., and these materials are as if you only choose the same size from a car carbon. Like coal, the cost will increase dramatically. Inferior brake pads, they will not use such high-end materials, so they can not guarantee the stability at high temperatures, and with the increase of speed, the heat is more, the temperature is higher, the link strength is lower, thus reducing the system Dynamic ability, expressed as the brake distance is extended. Therefore, if you drive the brake pads in the city at 20-60 km/h, it does not mean that you have the same stable braking distance performance at high speed. When the molecular chain is degraded at a high temperature, the wear is accelerated, which is why the service life of the general brand brake pads is very short in mountainous areas or in the case of frequent braking.

Question

Is the brake pad not noisy, it is soft, its service life is short?

Answer

No, this statement comes from the auto repair shop. There is noise, saying that the brake pads are hard, giving you a soft, no noise, but you are required to accept short-lived defects. If you have a long life like a taxi, it must be hard, you can only accept noise or grinding discs. In fact, these statements are all inaccurate. In addition to the proven formula of the original car, it has the ability to ensure low noise while ensuring long life. Most of the market is alone in making noise as the main goal, they are for the so-called market demand. These products have a very short life span of about 20,000 kilometers. As to whether it can guarantee the safe braking distance and the braking ability at high temperature in the emergency situation of the owner. That requires the owner's own judgment.

Question

Is there no noise in the brake pads of the original car?

Answer

Can only say that the odds are extremely low. Because the noise produces too many factors, the main ability of the brake pads is to ensure that the safety braking ability under various extreme road conditions remains stable.

Question

How do you feel the jitter when some brake pads are installed and braked on the brakes?

Answer

Just another pair of other ones, is the quality of the brake pads? The brake pads do not cause jitter. The reason for the jitter is mostly because the brake disc is deformed by hot and cold alternately under high temperature conditions, or the brake disc is warped after re-disc, which has nothing to do with the brake pad. As for why you changed one, the reason is that the latter is very compressible, and the product can absorb the warpage and deformation of the brake disc. In the original vehicle supporting standard, compressibility is an important project, which requires the brake pad to be compressible between 0.1 and 0.2 mm under normal braking force, so as to ensure the brake pads under emergency braking conditions. reaction speed. Therefore, considering the above considerations, if it is better to replace the brake pads because of the jitter, you may not be happy.
