Shear strength tester

This testing machine is mainly used in GB/T 22309-2008/ISO 6312:2001 Road Vehicles Brake Lining Disc brake Pad Assembly and Drum Brake Assembly Shear strength Test Standard.

Is the brake pad quiet or soft, resulting in a shorter lifespan? Let the brake pad manufacturer answer for you now!

Answer: No, many of these statements come from repair garages. There is noise, and it is said that the brake pads are hard. I will make them soft and quiet for you, but I require you to accept defects with a short lifespan. If you want a long lifespan like a taxi, it must be hard. You can only accept noise or a grinding wheel. In fact, these statements are all inaccurate. In addition to the mature formula that comes with the original car, it has the ability to ensure low noise while also ensuring a long service life. Most of the people on the market prioritize noise as their main target, in order to meet the so-called market demand. This type of product has a short lifespan, approximately 20000 to 40000 kilometers. As for whether it can ensure the safe braking distance and braking ability of car owners in emergency situations under high temperatures. That requires the owner's own judgment.

Is it possible that the brake pads provided with the original car are no longer noisy?

It can only be said that the probability is extremely low. Because there are too many factors that generate noise, the main ability of brake pads is to maintain stable safety braking capabilities under various extreme road conditions.

What is the reason for the feeling of shaking when applying the brakes after some brake pads are installed? Just change to another pair. Is it due to the quality of the brake pads?

The brake pads will not cause shaking. The reason for shaking is mostly due to the deformation of the brake disc during hot and cold alternation under high temperature conditions, or the warping of the brake disc after re disc processing, which is not related to the brake pads at all. As for why you should replace it, it is estimated that the reason is that the latter has great Compressibility, and the product can absorb the warpage and deformation of the brake disc. In the original vehicle matching standard, Compressibility is a very important item. It is required that the Compressibility of the brake pad should be between 0.1 and 0.2 mm under normal braking force, so as to ensure the reaction speed of the brake pad under emergency braking conditions. So, based on the above considerations, it would be great if the brake pads were replaced due to shaking, and you may not be happy.

The brake pads were installed very well at the beginning, why did they produce noise later on?

Based on the fact that the brake pads and brake discs are a pair of friction pairs, it is recommended to compare the performance of the brake pads after using them for 300-500 kilometers, as at this time, the brake pads and discs are basically in place. The noise generated during this time period is sometimes not caused by the brake pads. If noise is generated after prolonged use, it is necessary to determine the problem with the brake pads.
