Common sense of brake pads that you don't know
"There are too many brands of brake pads now", this is a very frequently heard sentence in the market.
"You don't lack products, what you lack is the ability to identify products." This is a sentence that the author often sighs. Especially as a brake pad manufacturer that has been developing and producing brake pads for many years, we always answer patiently when faced with some doubts.
There are many misunderstandings about brake pads in the market at present, and they are also questions that I often have to answer.
1. Is ceramic fiber added to the formula a ceramic formula?
no. Ceramic fiber is just one of the commonly used fibers for brake pads. There are also metal fibers, mineral fibers, wood fibers, aramid fibers, etc. Their function is to connect various fillers, just like the mud walls in rural areas. Like straw.
2. What is the noise of the brake pads?
Noise is mainly frequency resonance. If the natural frequencies of two materials or components are the same, resonance will easily occur. It is very simple to solve the noise of the brake pad alone, it is very simple to solve the service life alone, and it is also very simple to solve the problem of not hurting the disc alone. There are many factors that cause noise. The entire brake assembly system is the cause of noise. Improper selection of brake discs and serious disc wear can cause noise. In many cases, everyone has wronged the brake pads.
3. I feel that the one with more metal content is harder, and the harder it is, there must be more noise. Some auto repair shops say the same, right?
wrong. Many of these claims are from auto repair shops, which are not scientific. The original car of the United States is mainly semi-metallic, which contains a lot of metal. Have you heard a lot of noise? Noise is not directly related to softness and hardness. The grinding disc and noise just indicate that the product formula is immature and has nothing to do with the amount of metal. In fact, metal materials in the formula mainly play the role of connecting fillers and heat conduction. At the same time, their own hardness is not much different from that of discs, and will not cause major wear to discs. It is not what you see that really grinds discs and increases braking capacity. The metals you see are the abrasive fillers that you can’t see, which are harder than the brake discs. They are actually corundum, which is the same material as your common sandpaper and grinding wheels.
