Hello. The carbon black on the wheel hub belongs to the brake shoes, and the asbestos and carbon black dust produced when rubbing indicates that there is a problem with the brake shoes you install.

Fault Judgment: False Fault.

Cause analysis: the reason for the blackening of the wheel rim is that when the brake is braking, the brake caliper and the wheel disc rub against each other to grind some carbon powder, if the carbon powder is not removed in time, the aluminum alloy rim of the wheel will also heat up, and the heat causes the carbon powder to coke on the surface of the aluminum alloy rim, which becomes a layer of dark brown hard surface, which cannot be removed with water.

Solution: Rinse the rim frequently.

The wheels of the car are blackened, those are the dust of the brake pads, which is due to the powder that falls off the friction between the brake disc and the brake pads in the process of driving, don't worry about him, if you think it is not good-looking, you can brush the car and brush it off, and observe the thickness of the brake pads on time, so as not to affect the safety of driving.

Cause analysis: the reason for the blackening of the wheel rim is that when the brake is braking, the brake caliper and the wheel disc rub against each other to grind some carbon powder, if the carbon powder is not removed in time, the aluminum alloy rim of the wheel will also heat up, and the heat causes the carbon powder to coke on the surface of the aluminum alloy rim, which becomes a layer of dark brown hard surface, which cannot be removed with water.

As the driving time of the car increases, the temperature will increase during driving, and it is normal for the color to turn slightly black.

It's just that the friction is too much.

It is pleasant to keep the interior of the car clean when you use it, especially the new car looks more comfortable, but after using it for a while, you will find that the front tires and wheels will be a little black and will not be washed off when washing the car. What is the reason?

In fact, it is normal for the wheel hub to turn black. This is because some of the toner that was crushed off when driving on the brakes was stuck on it and was not cleaned up in time. In addition, the wheel hub will also heat up due to the friction of the tire when driving, causing the toner on it to stick to it, but if it is not treated, it will cause irreparable damage to the paint surface.

So why do many people don't like to wash wheels when they wash their cars? This is because the form of the wheel hub is becoming more and more complex nowadays, and some narrow empty spaces on the wheel hub are very difficult to clean, even with professional cleaning tools, it is difficult to master. Besides, this thing is relatively strong, and few people will take care of it.

What if I want to get rid of all the toner on it?

First of all, you need to use a professional cleaner, and you can clean it well by buying a bottle of HUB cleaner directly online. Cleaning can be broken down into the following steps.

1.Turn on the cleaner, spray evenly on the hub and let it sit for a while.

2.Then use a special hub to brush on the hub to accelerate the decomposition of the toner, and some purple liquid can be seen flowing down when brushing.

3.Finally, rinse the wheel directly with clean water or a high-pressure water gun.

You can also use some detergents that can clean heavy oil stains to clean the wheels, such as Mr. Wei Meng at home.

Wear gloves when using as this cleaner is corrosive. Then wet the hub with clean water, spray with detergent, and brush with a brush. However, the effect of using this cleaner is not particularly significant.

There are also some veteran drivers who say that toothpaste can also clean the toner on it, but it is more troublesome to use. Among these kinds, it is more convenient to use a hub cleaner. After all, this cleaner is specifically for stains on the wheels.

Of course, it can also prevent the wheel hub from blackening, but this requires the owner's diligence. The wheel hub is generally cleaned once a week or so, and then wiped with a sponge, which can well prevent the wheel from turning black.

Hot topic: odd and even public opinion polls.

The reason for the blackening of the sports wheel rim is that the brake brake is grinding down the toner from the brake caliper and rubbing against each other when braking, which was originally only gently covered on the surface of the aluminum alloy rim, but it was not often removed and accumulated for a while, because the car has been driving for a long time, the aluminum alloy rim will also heat up, and the heat causes the toner to coke on the surface of the aluminum alloy rim, and it becomes a layer of dark brown hard surface, which is indeed impossible to wash off with water.

To avoid this phenomenon, the car should be diligent in rinsing the rims when it is new, and the wheels should be washed at least once a week when the vehicle is driven every day, first rinsed with water, then brushed with a sponge with detergent, and then rinsed with plenty of water.

If the car has been driven for a while, and you are not usually diligent in cleaning and maintenance, and a layer of hard dark brown coke has formed on the rim, then you should use a stronger rim cleaner. After spraying a special detergent, you must wait for a while to allow the solvent to soften the coking, then brush it off with a sponge or coarse cloth, and then rinse it with clean water.

Choose a refreshing shape for easy maintenance.

Be careful, don't be in a hurry, some serious coking needs to be needed.

It takes two or three cleaning actions to completely remove it.
