The runaway car with a speed of 130 per hour is 7 years old. Professionals explain the reasons for brake failure in detail.

Red Net News January 19th(Reporter Xiao Shuai correspondent Wu Bofeng) "Li Qiang! Hold him back! " "resist! Hold on! Hold on! " On January 16th, an "extreme rescue" was really staged on the Hangchang Expressway in Hunan. Due to the brake failure, a car went out of control at a speed of 130 km/h. At the moment of life and death, Hunan high-speed traffic police risked their lives to crash into a police car, abruptly stopping the out-of-control car, and eliminating a huge safety hazard.

After the life-and-death rescue, the parties sent a banner to Liuyang Brigade of Changsha detachment of Provincial High Police Station.

The car is out of control on the high speed, and the driver is scared to ask for help from the high speed police.

On the afternoon of January 16, a white car with Xiang D license plate suddenly lost control in Jiangxi Province of Hangzhou-Changzhou Expressway, and was driving along Hangzhou-Changzhou Expressway at a speed of about 130 km/h, and was about to enter Hunan Province.

At 16: 41, the duty room of Liuyang Brigade of Changsha detachment of the Provincial High Police Station received the traffic police from Jiangxi Expressway, and through the video of the road network monitoring center, it was found that the car had passed the Daweishan South Road section of Hangchang Expressway, and then emergency rescue was quickly carried out.

The actual combat command center of Changsha detachment of the Provincial High Police immediately dispatched Li Qiang, a policeman of Liuyang Brigade, and Zeng Yiwei, an auxiliary police officer, to get on the expressway from Guandu Toll Station and meet them at the 671km section of Hangchang Expressway that the car is about to pass. Liu Zhenyu, the instructor of Liuyang Brigade, and Ye Zhang, a policeman, went to the Liuyang East Toll Station at 698km from Hangchang Expressway for support.

High-speed traffic police along Hangzhou-Changzhou Expressway sent police to stand by in front of each hub and intercommunication, and related departments such as obstacle clearing, rescue and first aid were synchronized. The actual combat center of Changsha detachment of the Provincial High Police Station quickly dispatched all high-speed traffic police brigades along the line to divert dangerous vehicles and contacted the brand of out-of-control cars to discuss technical issues.

Police cars escort out-of-control cars in tandem. Police extreme rescue at the moment of life and death.

At 16: 52, after Li Qiang found the out-of-control car, he immediately drove the police car in front of it. At 17: 16, Liu Zhenyu and Ye Zhang drove a police car and followed the out-of-control car to warn, and reminded passing vehicles to avoid by sounding sirens and shouting.

Two police cars in tandem escorted the out-of-control car into the Daowu Mountain Tunnel, but the situation was not optimistic-the car was still driving at a high speed, and there were two cars in parallel ahead. If you continue to pull forward, the out-of-control car will enter the large-flow section in front, which is very likely to lead to accidents, and it is also possible to be dangerous at the Bangshan Interchange 15 kilometers ahead.

At 17: 17, Liu Zhenyu made a decisive decision, seized the opportunity, and decisively informed the police car in front to slow down slowly with the rear of the vehicle to hold the car. "Li Qiang! Hold him back! Li Qiang! Hold him back! " Shouts echoed in the intercom.

After receiving the instruction, Li Qiang calmly handled it, gave full play to his driving skills, ignored his own safety, and braked the police car by clicking the brakes, causing the rear car to collide with the rear of the police car. After the body was violently hit, Li Qiang continued to control the direction steadily and let the car collide with the police car for the second time. After the two cars slowed down, they finally stopped in the driveway.

The police immediately stopped and warned, and carried out temporary traffic control on vehicles coming from the rear to avoid accidents. Subsequently, the car was towed away from the high speed and the road surface resumed normal traffic.

"Survive! Saving me is equivalent to saving the whole family! "

"The rest of my life!" Afterwards, the driver, Mr. Luo, still had a lingering fear and kept saying to the police: "Thank you, thank you! Thank you for saving my life! Saving me is equivalent to saving the whole family! " It turns out that Mr. Luo is about to become a father, and once an accident happens, it will be a devastating blow to the whole family. That night, after examination by the hospital, Mr. Luo and the civilian auxiliary police who were disposed of at the scene were not injured. After the incident, Mr. Luo sent a banner with the words "Saving people from danger, kindness is as heavy as a mountain" to Liuyang Brigade of Changsha detachment of Provincial High Police Station.

"I was most afraid when he hit my police car, but I can’t be afraid, because I want to do my best to handle this matter. I am wearing this police uniform, which is what I should do." Li Qiang said.

Professionals remind: car maintenance, should be checked on the road.

When the vehicle is on the road, the brakes suddenly fail. This is almost a scene that only appears in suspense movies, but it is actually staged in real life. During the interview afterwards, the relevant personnel told the reporter that this was the first time in his career that he had been exposed to such a situation. At the same time, the reporter also learned that the car with broken brakes is a used car, but it is said that the car is not too old and should be purchased in 2017. "It may be driven more frequently", and the specific reason for the brake failure is still under investigation.

Brake failure, what is the general cause? The reporter also consulted several 4S car dealers. According to relevant professionals, there are many reasons for brake failure: for example, there are too many impurities in the brake master cylinder, the seal is not tight, the vacuum booster pump fails, and the brake oil is too dirty, which may lead to air resistance and oil leakage in the brake master cylinder or the sub-cylinder, which leads to brake failure; In addition, if improper operation leads to mechanical failure, long-term downhill will cause friction and heat generation of brake pads and carbonization of brake hub, resulting in complete failure of braking function; Or in the case of serious overload, the acceleration of gravity increases the inertia of the vehicle, which directly leads to brake failure.

So for our car owners, how to avoid this extreme situation. Relevant professionals suggest: one is to do maintenance frequently, and the other is to remember to check before departure. Especially before long-distance travel, remember to make preparations for vehicle inspection before departure. It not only includes checking the normal operation of brake system, such as brake oil and brake pads; You should also check the tires for bulging, damage and tire pressure. The next step is to check the wearing parts such as oil and filter elements to ensure that they operate normally. Finally, check the spare tire and vehicle-mounted tools in case of emergency.
