What should I do if the brakes suddenly fail on the highway?

What should I do if the brakes suddenly fail at high speed?

First of all, if this happens, our first step should be to turn on the double flash, because in this way, we can be the passing vehicles next to you, can notice that their vehicles are brakes, can play some warning role, if there is a vehicle is very close, they will distance themselves from you, know how to avoid, so that the danger is relatively low. In addition, when the brakes fail, we may feel that since the brakes have failed, we are no longer stepping on the brakes, which is very incorrect. Because brake failure is generally good and bad, even if we know that the brake is failing, we must continue to step on the brake, because you may not find that your brake is suddenly good again.

And if you press the brakes more, it can also recover this problem, because his brake fluid line is also related to how often you apply the brakes.

If it doesn't work to keep applying the brakes, we can do something else. For example, the use of engine braking this method to reduce the speed of the car, so that we say that we have been hanging on the gear but do not step on the accelerator, in this way, some internal resistance in our engine also has some braking effect on its gears, so that the car can gradually stop. Of course, this method is not completely useful, so at this time we can also take both feet on the clutch, if it is an automatic transmission, it is easier to operate, but in manual mode, we must not step on the accelerator, to control the direction on it.

When these methods are useless, we must take, pull the handbrake to slow down, but this method still has the problem of attention, such as when we pull the handbrake, we can't pull too hard at once, directly to the end or, the speed is too fast, because the car also has inertia, these problems, if once pulled too fast, or pulled too dead, we will, the wire rope to break, so that our handbrake is useless. There is also the fact that when we pull the handbrake, we should not push too hard when hitting the direction, because when we pull the handbrake, the rear wheel of our car has been locked, and if the steering wheel is slammed, it will cause side slip and other dangers.

If the speed of the car does not decrease until the end, we have to use some obstacles or friction to reduce the speed of the car, but this method is more dangerous, this situation is only suitable for all situations have been tried before using this situation. Because, generally speaking, if his obstacles block the car, it will cause some dangers, in fact, the most important thing is that when encountering these situations, we must not panic too much, be too anxious, and calm down. In fact, the danger can be avoided, we should not be too anxious to forget how to operate, panic, this can only cause more serious consequences.

Although the probability of brake failure at high speed is very small in daily driving, it will cause very serious consequences if it is not handled properly, so it is very necessary to master some emergency braking measures in advance. There are three main causes of brake failure:

1、.Due to severe overload, under the action of gravitational acceleration, the inertia of vehicle motion is increased, which directly leads to brake failure.

2.Lack of necessary maintenance of the brake system, too many impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, excessive dirt of brake fluid or air resistance after mixing and heating of several brake fluids, oil leakage of the brake master cylinder or sub-cylinder, air leakage of the air tank or pipeline interface.

3. Due to improper operation, the parts fail, such as long-term downhill will cause the brake pads to rub and heat, the brake hub to carbonize, and the brake function to completely fail.

Downshift braking. Manual transmission car can also be forced to downshift deceleration stop, the specific method is to directly hang into the 2nd gear, and then release the throttle to lift the clutch, then the vehicle will have a feeling of sudden braking, and then wait for the opportunity to hang into the 1st gear, at this time the electric door can be turned off, and the vehicle can be stopped by using the effect of engine cylinder compression.

If the brakes fail in some downhill and other dangerous road sections, in order to prevent the danger from further expanding, if necessary, you can use obstacles such as sand and mud piles, grass piles, road ditches, woods, and rocks on the side of the road to resist the vehicle and stop.

Handbrake brake. After the brake fails, the handbrake can be used to brake, and the correct way is to slowly pull up the handbrake, and make the vehicle slow down and stop by several times of tensioning, loosening, tightening, and loosening. It should be noted that the safety button of the hand brake handle should be pressed into the hand brake handle when pulling the hand brake handle, so that the hand brake handle can operate freely in the process of tensioning and relaxation, and prevent the hand brake from locking when tightening.

Emergency self-help measures.

1. The best way to protect the back seat is to quickly stretch out one foot forward, put it on the back of the chair in front of you, bend your elbows in front of your chest, spread your hands to protect your head and face, and press your back back on the chair.

2. Seat belts can prevent passengers from rushing to the windshield during emergency braking, if you are not wearing a seat belt, it is best not to try to resist the collision, which may be more serious than going with the flow of injuries, because the deceleration and collision are more sudden. When reversing to the collision point, you should move away from the steering wheel as early as possible, with your arms between your chest and your head in your hands.

3. Here we also want to emphasize that if there is a car accident or emergency braking, you should quickly push the armrest or the back of the chair forward with both hands, and push forward with both feet one after the other, so that the impact force is consumed and the speed of the body rushing forward is buffered, so as to reduce the degree of damage. Do not shout when colliding, you should close your lips tightly and clench your teeth to avoid biting your tongue when colliding. There is a high chance of a car crashing and a fire occurring, so as soon as the impact stops, everyone should try to get out of the car as soon as possible.

4. According to the relevant data, it is proved that the co-pilot seat is the most dangerous seat, if you sit there, you should first lie on the seat with your head in your hands, or clench your hands into fists, protect your forehead with your wrists, and bend your knees to protect your abdomen and chest.

Keep calm and turn on the double flash.

Especially when driving at high speeds, remember to be in a hurry. Calm your mood first, turn on the double flash, warn the next vehicle away from you, and at the same time keep trying to step on the brakes (even if the failure is in a bad condition), it is likely that the brake fluid problem or other problems caused by temporary failure, and even if you feel that the car is out of order, in fact, the braking force is not all gone. Take 10,000 steps back and say, in that situation, it's better to keep trying than not doing anything.

Use engine braking.

Many old drivers who drive manual transmissions should know that when the brakes are not good, the high speed of the low-gear anti-drag engine is used to brake, and the automatic transmission is the same, constantly reducing the gear to brake. If the speed was very fast at that time, due to the protection of the gearbox by the vehicle, it was likely that the low gear could not be hung and had to be used in other ways.

Use the handbrake with caution. When the brakes fail, using the handbrake can save lives or kill people, so be cautious.

Directly linked to the handbrake is the parking system is not the braking system, only as a last resort, and at a high speed, the handbrake will cause the rear wheels to lock, resulting in the vehicle losing control and rollover. However, if it is an electronic handbrake type, the overall will be better (or be cautious), because it is equipped with an electronic handbrake and will also be equipped with a dynamic emergency braking function, which can be used to hold down the handbrake when the speed is low, and the ESP will brake the wheels.

Avoid turning off the heat. Once the vehicle is turned off, the brake assist will disappear, and the braking force will deteriorate, and at the same time, the steering power will also disappear, and the direction will not be easy to control.

Look for a safe haven.

On many highways, we have seen evasion lanes, which are all prepared for situations such as brake failure. Of course, it depends on luck to want a safe haven lane, not just to show it up.

If the above methods are not possible, you can only use your own body to rub against obstacles such as guardrails as a last resort, so as to force deceleration.

If there is no emergency shelter lane on the highway and the car cannot be stopped, in my case, the first thing is to pull the handbrake and immediately assess the situation ahead, the risk ahead, and calculate the best evacuation plan ahead. Second, the eyes should be as far away as possible, analyze all possible treatment options, and do not move around and hang in neutral. Let the car coast on its own and slow down to a stop.

If you need to stop in an emergency, you can also hit the side of the barrier on the hard shoulder, so that the body and the barrier friction effect to stop the car, after all, emergency life-saving is important.

Stay calm and don't panic. The speed on the highway is already fast, and the brakes suddenly fail, so you must be particularly flustered. As the saying goes, people are panicked and unwise.

The more panicked you are, the easier it is to get scrambling and making mistakes, which can lead to catastrophe. Therefore, staying calm, driving calmly, seeing the traffic in front of you, and avoiding traffic jams as much as possible are the key first steps.

If there are many vehicles in front of the car, then you can slow down the car by grabbing the low-speed gear, and the downshift span should not be too large, and it is best to lower the gears one by one to prevent damage to the gearbox. You can also slow down the car by slowly pulling the handbrake, and you must not tighten the handbrake all at once, which is easy to make the car flick and roll over, which is very dangerous. If there is a brake failure when going downhill, it may cause a stall, and you should immediately observe if there is a buffer parking area ahead.

If you don't have to do everything you can to reduce your speed, you can apply the brakes, tighten the handbrake gradually, hold the steering wheel tightly, and pull the car to a stop with one side of the body against the roadside obstacle.

First of all, you must stay calm, then turn on the double flashes to make the vehicles behind you visible, then downshift and slow down, and then quickly look for the avoidance lane, not only to protect your own safety, but also to be careful of the vehicles in front.

At this time, you can take the emergency channel, and you should put down the handbrake and step on the clutch, which can slowly reduce the speed, and after the speed is lowered, the owner should immediately go to a safe place, do not stay in the car, and should immediately call the police for help.

Don't panic, you can turn on the double flash, so that people can know that they want to call for help, and they should wave to the passing vehicles, try to slow down as slowly, and then slowly apply the brakes when slowing down. You can get a good rescue. Or drive steadily and give 110 dozens**.

Ask for help.

You should quickly disengage from the high-speed gear, shift the high-speed gear into the low-speed gear, and just get up and pull the handbrake. Then immediately turn on the double flashing lights and pull over. If possible, you can place some parking signs next to it to attract the attention of others, so as to avoid traffic accidents.

If you suddenly encounter brake failure on the highway, then you should not panic, because there are emergency evacuation channels on the highway, so you just need to keep driving to this road.

If the brakes fail at high speeds, you should first gradually reduce the speed of the car, release the accelerator, and then use the handbrake so that the speed can be reduced without directly rolling over.

Don't panic, be calm. Grasp the direction, don't change lanes quickly, be sure to step on the clutch slowly, and press the clutch when the speed slows down, and pull the handbrake up.

If the brakes fail at high speeds, you need to hold the steering wheel tightly, and then move as much as possible to the next fence to minimize the damage, and you should also pay attention to pulling the handbrake.

At this time, it is necessary to change the high-speed to low-speed gear, and then use the handbrake comprehensively, but not too tightly, nor too loosely, to properly pull the handbrake, do not let the car tires lock, protect your body, do not get hurt.

If the brakes suddenly fail on the highway, first of all, we should turn on our double flashes to let everyone know that this is a dangerous car, and secondly, we must call the police, and we must drive at a constant speed on the highway.

Stay calm, let go of the throttle, and then we can use downshifts or road resistance to reduce the speed of the car, and then go to a safe place and wait for help.

At this time, you should immediately call the traffic police, be sure to lower the gear of driving, and try to pull over, if there is a buffer belt around, drive to the buffer belt.

You should slowly reduce the speed of your vehicle, then slowly change lanes to the far right, and then immediately call the roadside assistance company or contact the police at the highway.

Choose an emergency lane, slow down slowly to stop the car, and pay attention to the use of lights to remind surrounding vehicles to take shelter.

If you encounter such a thing, you should call the police in time and let the police deal with it, or directly call the towing company to tow the car away.

You should turn the steering wheel, try to drive to a place where no one is around, dial ** in time, and seek help from others.

When the vehicle is driving at high speed, the brakes fail: first turn on the double flashing headlights to remind the vehicles coming behind to keep a safe distance to avoid causing secondary accidents; Finding emergency or escape routes; High-speed brake failure: First, don't panic, hold the steering wheel with both hands and control the vehicle; In case there's an emergency ahead, you'll need to quickly reduce your speed.

Measures to deal with brake failure of high-speed vehicles:

1. Turn on the double flashing headlights to remind the rear car to keep a safe distance to avoid secondary accidents.

At this time, the first thing to do is to observe the road conditions and avoid places with many vehicles. Generally, when the double flashing lights are turned on, the road vehicles will give way to the road disturbance.

2.Look for emergency or escape routes.

Many highways have speed bumps specifically for brake failure and breakdown vehicles. If there is, it is basically safe.

3.When high-speed brakes fail, don't panic in the first place. Grab the steering wheel with both hands and control the vehicle.

If it is a manual transmission model, it can change from high gear to low gear, and use the power of the engine itself to restrict the speed; In the case of automatic transmission models, many models are also equipped with a manual mode. For example, there is a 6-speed automatic manual gearbox, and when switched to manual mode, there is a "-" symbol next to the gearbox. Some CVT models also have L1 and L2 gears.

Switching to manual mode works on the same principle as on manual transmission models, with a gradual reduction in gears so that the engine revs are quickly reduced in low mode.

4.In case there's an emergency ahead, you'll need to quickly reduce your speed.

The mechanical handbrake type can pull the handbrake slightly, only slightly, otherwise the vehicle will lose control of the tail. At this time, there is an emergency lane on the highway. When the speed of the vehicle is slightly reduced, you can use the right side of the vehicle to approach the guardrail and use the friction of the vehicle to reduce the vehicle speed.

This must have some driving skills. If not operated properly, the vehicle can lose control, causing more serious injuries.
