Brake failure frequently causes accidents, and brake discs become the biggest hidden danger?
What are you most afraid of when driving? The brakes, of course! Especially at high speed, brake failure can lead to serious consequences!
According to relevant statistics, in recent years, the annual traffic accidents in China are more than 300,000, of which 30 percent are caused by brake failure. The following are some of the accidents displayed in the Internet search:
As the most important safety guarantee of the vehicle, the importance of the brake for driving safety is self-evident, so for the maintenance of the brake system, every owner can not have the slightest slack.
How long will my brake pads last? This is one of the most concerned about most owners but owners often only pay attention to the brake pad, but ignore its iron brother brake disc in fact, the brake disc also needs to be replaced regularly Oh!
In the braking process of the vehicle, the brake disc and the brake pad are worn together, but the brake disc is more wear-resistant than the brake pad, so that people only need to replace the illusion of the brake pad. In fact, the brake disc is the same as the brake pad, and there is a wear limit, once reached should be replaced immediately!
Otherwise, it may cause deformation and generate jitter cracks, affect braking performance, and even brake failure in serious cases, leading to frequent accidents!
01
Replacement mileage of brake disc
Generally speaking, the brake pads (that is, the two brake calipers) need to be replaced about 340,000 kilometers, and the replacement mileage of the brake disc is generally about 780,000 kilometers, of course, the replacement mileage is not completely absolute, according to the owner's own driving habits (whether you like the brake) road conditions and other factors to decide.
In addition to the mileage mentioned above, there are the following situations to pay attention to:
Check whether the warning light of the brake disc is on. If it is on, it means that the loss has reached the limit and it needs to be replaced immediately;
Check the brake disc for deep grooves. Replace the brake disc when the combined thickness of the deep grooves on both sides exceeds 3 mm;
If the replacement frequency of the brake pad is very high, it is necessary to check the thickness of the brake disc, because the use of the brake pad and the use of the brake disc is relatively worn.

How to buy high quality brake disc?
The service life and quality of the brake disc is proportional to the current market of poor quality brake disc everywhere, many owners do not know it is easy to be if the long-term use of the hole, will be caused by friction of high temperature deformation, reduce the brake performance, thus affecting the safety of driving.
Therefore, it is important to know how to choose a good brake disc!
Choose regular products
Before buying goods, please be sure to verify the vehicle model displacement and other information, to ensure that you buy the right type of accessories.
Before the replacement of the brake disc to check whether the replacement is pure accessories, product packaging integrity of the anti-counterfeiting signs and packaging identification and the identification of the brake disc is consistent, product model is consistent with the quality certificate content of the regular brand brake disc, packaging printing is relatively clear, there is a certificate of qualification in the packaging box.
Complete sets of choose and buy
Brake disc should be purchased in complete sets, because when the front brake disc is replaced, a total of 2 front left and right wheels need to be replaced at the same time to ensure the stability of the braking effect, and the rear brake disc is the same.
In addition, the replacement of the brake disc must be replaced at the same time the two wheels of the coaxial, the replacement of the new brake disc to avoid the strong brake needs to be run in through about 1000 kilometers, in order to make the brake pad and brake disc to achieve the best working state.
The perforated marking brake disc has good heat dissipation performance
At present, the most widely used is the ventilated brake disc, which is generally used in the front wheel of a car. The ventilated brake disc is two pieces of iron sandwiced with a lot of ventilated grids. When the car is driving, the air flows through the middle grid, which can quickly cool down
Car brake effect from good to bad in order: perforated ventilated brake disc ventilated brake disc solid brake disc drum brake disc.
