Common sense of brake pads that you don't know
4. Why are there grooves on some discs? Are the brake pads hard?
There are national standards for the hardness of brake pads, which are basically between 35 and 70 Shore hardness. This hardness is not the main cause of wear on your brake discs. The wear-increasing agent in the brake pads is the main component of the wear disc. Soft and hard brake pads are not the cause of severe disc wear, the culprit is low-cost wear additives.
5. The brake pads I bought for 70 yuan are also very effective, right? Good braking effect
It is very simple to realize the braking ability of the brake pads. What it needs is to maintain the stability of the brakes under high temperature, emergency, high speed, and rain conditions. This is the most difficult thing. The original car requires more indicators such as comfort, noise, environmental protection, etc., which makes the brake pads even more difficult. Therefore, your simple normal driving feels good, but it does not mean that its safety performance can reach the effect of the brake pads on your original car in various emergency situations. To be honest, the original car of your private car only needs to be replaced with a set of brake pads after 4 or 5 years. If it is only 70 yuan as you said, do you think this profit can support the brake pad factory? Of course not, what can't be done? you know.
Sixth, as long as there is no noise from the brake pads, wouldn’t it be enough to stop the car? Is it that mysterious?
As mentioned above, it is very simple to solve the noise alone. But the main function of brake pads is not noise, but safety. Now the market really pays too much attention to the noise and ignores the main function of the brake pads. As for what everyone said, is it enough to stop the car? That's right, just stop the car, but you may not have thought that you can stop the car on flat roads, you can stop the car at normal speeds, but can you stop the car in emergency braking situations? Can you stop the car under the high temperature of continuous braking on the winding mountain road? Can you guarantee the braking distance at 100 kilometers per hour in the rain? What the original car brake pads must guarantee is the stability of the braking ability when we need safety most. At this point, I believe that many car owners who think that it is enough to brake the car have not thought about it.
