The "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (referred to as the "New Communications Regulations") that came into effect on January 1, 2013, imposes legal restrictions on the more prominent traffic problems, and penalties for violations are even more severe. In the new rules and regulations, the severe punishment for the fine of RMB 200 and a score of 6 on the “yellow light” was widely discussed. When a traffic light without a countdown countdown is encountered, the driver is most likely to experience a sudden attack with the green light suddenly turning yellow. It often comes as a surprise and an emergency brake.

Severe penalties do have a deterrent effect on drivers who like to “grab the lights.” Since the implementation of the new rules, we have noticed that more and more vehicles have become cautious when they cross the intersection, and the speed has been reduced considerably. However, in order to avoid being penalized for the yellow light, the implementation of the new rules also led to a significant increase in the probability of an emergency brake before the traffic light. Some people even think that this will lead to a significant increase in rear-end accidents. Today we temporarily put down this controversial topic, or talk about how our car should respond under the new regulatory environment. With more frequent braking and greater probability of rear-end collisions, while adjusting the driving mentality, we should also ask whether the vehicle's braking system is ready.

In addition to the driver's own safety awareness, the efficiency of the braking system is the most basic and the most influential factor in ensuring the safety of the car. Since the new rules have raised the two issues of emergency braking and rear-end to a new height, we also hope that everyone will take this opportunity to check the brake system of their own cars and regularly check and maintain the vehicle brake system. Drivers should develop good habits. But in fact, the brake system is not as important as the engine maintenance. Some people even think that the brake system of the car is very durable and does not have to be inspected for several years. The misconceptions on these concepts should first be changed.

Due to the negligence of the maintenance of the brake system, some owners often wait until the brake system works abnormally to perform maintenance. It is very likely that the brake failure caused by the failure of the brake system may even have serious consequences. Therefore, the brake system can only be checked and maintained regularly to ensure its normal operation, thus ensuring safe driving.

At present, mainstream commercial vehicles in the market, whether disc brakes or drum brakes, work on the principle that brake friction discs and brake discs or brake shoes and brake drums rub against each other, converting kinetic energy into Heat energy to achieve braking effect. During the friction process, the brake system wears. In general, the wear of the brake system has a lot to do with the weight of the vehicle, road conditions and driving style. The more frequently the brake is used, the more the brake system wears out. Large, it also needs more timely maintenance.

Many people will use the dashboard brake system warning light as the basis for the replacement of brake pads, but if you wait until this time is very dangerous. Because only some high-grade vehicles use sensors that directly sense the thickness of the brake shoe, most warning warnings for civilian vehicles are that the brake friction plate is almost completely worn out and the brake fluid level is drastically reduced. The warning light is on.

Therefore, we recommend that you check whether the brake pads are still full during each routine maintenance. If there is any signs of wear, you should replace the near-life limit dynamic friction plates earlier instead of just believing the warning lights.

If the amount of brake fluid is insufficient to allow air to enter, braking becomes insensitive. We recommend that domestic vehicle owners check the brake fluid once a month, pay attention to whether there is a significant drop in the brake fluid level, and whether the quality deteriorates. If so, it should be added or replaced in a timely manner. In addition, after long-distance running or after off-road, stones or other obstacles on the road may damage the brake fluid line and cause leakage. Therefore, after each long-distance driving, the condition of the brake fluid should be checked in time. In particular, observe whether the brake fluid is in the chassis. Missing phenomenon.

Brake fluid has a strong water absorption. If moisture enters the brake fluid, frictional high temperatures during braking will vaporize the water, and the gas will be compressed in the brake fluid. This will result in brake failure or even failure. . During the rainy season and other seasons when the air humidity is high, some brake fluids absorb water more seriously. After passing through water and other driving environments, they also need to be checked in time. If the brake fluid is obviously deteriorating, it must be replaced as soon as possible.

Brake linings and brake discs also need to be replaced when worn to a certain degree to ensure that braking efficiency is not affected. Since the wear of the brake system is affected by many factors, in general, the life of the brake disc is approximately 50,000 kilometers in urban conditions, and the life of the brake lining is approximately 30,000 kilometers, but this value is not Not absolute, if the driving environment is more complex, the frequency of replacement should be shortened. In short, it is still one sentence: The habit of regular inspection and timely maintenance is the most important.

While checking the brake lining, also check the wear condition of the brake disc or drum. If the dent on the contact surface should be repaired or replaced in time to ensure enough contact area with the brake lining.

Does having a good braking system mean nothing?

With the implementation of the new rules, we introduce another knowledge about the maintenance of the brake system. In addition, even if your car has a powerful, efficient braking system, it cannot overcome the laws of physics. Even if the car in motion fully brakes, it needs to slide a certain distance from deceleration to complete stop. We hope that everyone understands the truth: Even if the brake system of the car is invulnerable, the driver still has to take responsibility. Otherwise, it is still difficult to avoid the yellow light, red light, or rear-end collision.

According to the data gathered by actual testing of [Phoenix], we chose Porsche 911, Volkswagen New Lagyi and Huatai Baolig to represent three models of performance sports cars, ordinary family cars and SUVs under emergency braking. Performance. With full braking at a speed of 30km/h, even the most powerful Porsche 911 braking distance among the three cars exceeds 3 meters, and the two ordinary people's ordinary cars are close to 4 meters.

It should be noted that the test distance is the deceleration of the vehicle, that is, the calculation of the braking system begins. In the actual driving environment, the driver needs reaction time from finding the yellow light and then performing the braking action. We assume that the driver's reaction time is 1 second. If the vehicle speed is 30km/h, the vehicle will advance 8.33 meters within one second. After the two are superimposed, even Porsche, which costs nearly 2 million yuan, needs to be At least 11.7 meters to completely stop the car, and two ordinary civilian vehicles, especially the relatively heavy SUV required more than 12 meters.

This is still a trained test rider. In the ideal situation where the vehicle is unloaded under full braking, the braking results obtained will be increased. If the conditions are replaced by ordinary drivers, the road is slippery, and the vehicle is fully loaded, the braking distance will continue to increase. Even if it is prudent to keep the speed at 30km/h (which is already slower than most urban commutes), it is still difficult to guarantee that the “lights” will be punished.

So, please remember the following two suggestions: First of all, make sure your braking system is in good condition at all times, and don't lose the chain at the critical moment. Regardless of whether or not you are plagued by yellow light changes, a well-functioning brake system is an important safety factor for your safety.

Second, don’t be too confident. No matter how expensive your car is, it stops completely longer than you think. Whether it is to avoid accidents or to avoid being punished, predictive deceleration and judgment of road conditions are all necessary for the driver to pass through the intersection. Since we cannot temporarily change to be scared by the yellow light, let us be cautious before we get on the road.
