Brake pads are a very important part of a car, and it is an indispensable part in a car. Sometimes the quality of the selected brake pads is related to the personal safety of our car when driving, but sometimes when the brake pads are used Dust fall often occurs, so what is the situation of dust fall on the brake pads?

What is the situation of dust falling on the brake pads?

1. What is ash from brake pads?

1. When the vehicle is braking, the friction powder produced by the brake pads and the brake disc is dust. Usually, when some car owners see that the wheel hub is dyed black by the powder falling from the brake pads, they think that the brake pads have been severely powdered. This is a misunderstanding of everyone's understanding of brake pads.

2. What is the situation of dust falling on the brake pads?

1. At present, most of the brake pads are made of low-metal materials, which have the characteristics of good heat resistance, strong absorption per unit area, and large thermal conductivity, which can adapt to the braking conditions of the car during high-speed and high-load operation. However, there is a relatively large drop in ash fall. The brake pads of Japanese and Korean cars are mostly made of ceramic material. The ash of this material is not absorbed, and the dust is scattered after rubbing. The disadvantage of this material is its high cost.

2. The wheel hub looks a lot of gray, which does not mean that the brake pads are bad. Because, all brake pads will fall off the ash, but due to the difference in the structure of the wheel hub, more or less ash is attached to the wheel hub.

The friction of the brake pads containing metal parts will generate static electricity, which will attract the dust material that has been rubbed off to form black ash on the wheel hub. However, the ceramic material will not be adsorbed on the wheel hub, and will float into the air after friction, so there is not much ash falling on the wheel hub.
