The reason for the blackening of the rim of a sports car is that when the brake is in the braking action, the carbon powder that is rubbed between the brake calipers and rubbed against each other is originally only lightly covered on the surface of the aluminum alloy rim, but it is not often removed and accumulated. After a while, because the car has been running for a long time, the aluminum alloy rim will also heat up. This heat causes the carbon powder to coke on the surface of the aluminum alloy rim, which turns into a dark brown hard surface, which is indeed impossible to use with water. Washed away.
Why only the front wheels will meet and the rear wheels will not? That's because when braking, the center of gravity of the vehicle moves forward, and all the weight is concentrated toward the front of the car, causing a heavier burden on the front brake, so the brakes will wear much more toner than the rear wheels.
To avoid such a phenomenon, you should wash the rims diligently when the car is new, and wash the rims at least once a week when you drive a car every day, first rinse with clean water, and then use a detergent to wash with a sponge, and then Then rinse with plenty of water.
If the car has been driving for a period of time, and it is usually not diligent in cleaning and maintenance, and a layer of hard dark brown coking has formed on the rim, then use a stronger rim cleaner. It is necessary to be resistant to remove the coking. After spraying the special detergent, you must wait a while to let the solvent soften the coking, then brush it off with a sponge or coarse cloth, and then rinse with clean water as well.
It should be noted that you must not be impatient, some serious coking requires two or three cleaning actions to be completely removed. People who don’t like to maintain their car by themselves, it’s best to choose a “fresh” shape that is simple and clear, without too many complicated structures, and without a bunch of small screws when buying the rims for the first time. It will be maintained and cleaned in the future. It's easier to get up. The copyright belongs to the author www.jihoowheels.com
