One of the parts of a car that is prone to rust is the brake disc.Of course, if you are driving a sports car, a performance car, or you have changed the carbon ceramic brake discs yourself, then it's another matter.What I'm talking about here is most of the family cars on our road. The brake discs of these cars are usually made of iron, so they are very easy to rust after encountering rain.

Moreover, the brake system is a very important part of the car, and there can be no mistakes.If the brake system fails while the vehicle is driving, the consequences are unimaginable. Although the rusty brake disc will not cause the brake system to fail completely, if it is a rusty brake disc, the braking effect will be greatly reduced when braking.

Hearing this, can't you wait to see if the brake discs of your car show any signs of rust?In fact, don't panic too much. If it is some slight rust, don't worry at all. It may just be caused by you leaving the vehicle for too long.

Here you may have to ask: how to judge whether the rust on the brake disc of your car will affect the braking effect?

Answer: It's actually very simple. If you find that there is rust on the brake discs of your car, you only need to step on a few more brakes on a safe and empty road, and then see if the previous rust has been rubbed off. Generally, slight rust can be rubbed off by the brake calipers by stepping on a few more brakes.And if you find that you have stepped on the brake many times and there is still a lot of rust on the brake disc, then you must pay attention.Be sure to go to the 4S store in time for repair. Usually the 4S store will polish the brake discs and polish off the rust, so that there will be no problems.
