We often encounter the problem of rust, but will it certainly affect the brakes, or must be a quality problem? Not really.

Why does a car's brake disc rust after only a few years of use? How to deal with?

Many people do not understand why the brake disc will rust, worried that it will cause a decline in braking performance. In fact, now most of the family car brake disc is cast iron material, unlike the body surface as anti-rust treatment, and long-term exposure to the sun and rain, the working environment is bad, especially for a long time to park, the surface is easy to generate some rust. This kind of situation can also be seen in the new car store of the 4S store. These are new cars, but this kind of situation will occur if parked outdoors for a long time.

General brake disc rust is actually a normal phenomenon, with no necessary connection to the quality. However, there is a certain impact on the brake system, but there is no need to make a fuss, these problems owners can deal with their own.

If it is only a slight rust, we can use continuous braking method when driving rust removal, because disc brakes rely on the friction between brake calipers and brake pads to brake, rust can be worn off in multiple braking, of course, to do this method under the safe road section. This is the method of "polishing" a slight rust.

If the rust is serious, the above method is not applicable, braking will also find the brake pedal, steering wheel and other obvious jitter, this situation will have to go to special treatment, because the rust is too "stubborn", not only "polishing", but also accelerate the wear of brake pad. In this case, we need to find a repair factory to remove the brake disc and polish it, and clean the rust.

Of course, if the rust is too severe, even the repair shop can do nothing about it, so the owner of the car is often in the state of the brake disc maintenance must be done once every two months. In order to avoid causing serious corrosion of the brake disc, but also at any time to drive on the road.

Besides rust, what problems should the car brake system pay attention to?

In addition to the conditions we can easily see such as rust, we should pay attention to two aspects of the inspection of the brake system. The first is the thickness of the brake pads. The thickness of the brake pads is about two or three millimeters, which must be replaced. At present, many models in the brake pad is too thin when the position of the instrument brake alarm light will be prompted, the relative self-inspection is more convenient. And the vehicle without brake alarm need not worry, because the brake calipers will be near the thinnest position of the protruding position, forming a brake abnormal sound to remind the driver.

If it is a drum brake, you can listen to the light brake at the same time accompanied by the "iron rub iron" silk sound, or view the position of the hand brake higher, the brake pad must be replaced immediately.

Another aspect of the brake system inspection to pay attention to is the brake fluid, high quality brake fluid is the basic safety and good brake system power condition. The brake fluid should be replaced regularly. Any brake fluid that is released from the system should be discarded and not reused. The best quality brake fluid on the market should be purchased. If the brake fluid is dirty, drain and flush the entire system, then fill the main cylinder with fresh fluid. If you're running short of brake fluid for a long period of time, and you're adding it, then obviously there's something wrong with your brake system and you should have it checked out.
