When the brakes of a manual transmission car fail, the engine can brake, but what about the automati

Automatic transmission cars are present with engine braking.

The so-called "engine braking" is a term for driving behavior, which refers to the use of the resistance generated by the engine when it is running to effectively control the speed of the vehicle, and the throttle loosening method is generally used to achieve engine braking. Generally, it is mainly used on highways or national highways, that is, when the driving speed is high, if you find that the traffic in front is large, you need to slow down or avoid in advance, then you can take this way, (the premise is, of course, to slide with gear). Its advantages are that it can avoid frequent gear changes, reduce driver fatigue, save fuel and improve the economy of the vehicle.

Automatic transmissions generally have a low-speed hill climb gear, which can force the vehicle from D gear to gear and gently pull the handbrake.

Forced to lower the vehicle from D gear to 1, slowly pull the handbrake, and brake with the handbrake.

1.Take advantage of obstacles. If you can't grab it in the low gear, don't panic, at this time, you should carefully observe the road conditions, see if there are mountains, rocks, trees or dirt slopes around, and use the bumper, compartment and other rigid parts of the car to rub and collide with obstacles on the side of the road to achieve the purpose of forced parking.

It is necessary to pay attention to the steering wheel with both hands to avoid shaking the steering wheel and injuring the hand bones.

2.Try pressing the brake pedal a few more times to increase the chance that braking force will recover. When you find that the brake pedal is failing, you must try to release it and then press the brake pedal, which can make the brake equipment containing air in the oil pipe add pressure, and then with repeated pressure, you can increase the chance of braking force recovery.

3.Intermittent and short-term use of the handbrake to see clearly, it is not a one-time pull of the handbrake and it is over, it is an intermittent short-term handbrake pull. The vehicle downshifts, and after the speed of the vehicle drops, the handbrake is used intermittently for a short time, relying on the handbrake to finally bring the vehicle to a complete stop.

Remember, be sure to pull the handbrake quickly and then put it down immediately, and do it quickly. Because if the handbrake is forcibly pulled, it will cause the handbrake line to be broken or the vehicle to lose control. Therefore, the car can only be forced to automatically downshift by frequently pulling the handbrake.

4.Turn on the emergency lights to alert nearby vehicles. In the emergency situation of brake failure, many drivers only think about how to slow down the vehicle, and ignore the warning of the surrounding vehicles.

There is nothing wrong with this, but if you take slowing down measures and turn on the double flashes and honking the horn to attract the attention of the surrounding vehicles, the success rate of self-rescue will be higher.

5.Stay calm at all times. When the brake system is found to be out of order, the driver must be calm, do not panic because of the loss of control, and do not step on the brake because of the failure, which is counterproductive. Calm, calm, and adjust your mentality can minimize losses.

The driver should calmly and quickly disengage from the high-speed gear, shift the high-speed gear to the low-speed gear, and use the traction resistance of the engine to reduce the speed of the vehicle. In addition, the handbrake should be used in conjunction with the low-speed gear change, but it should be noted that the handbrake cannot be tightened at one time, nor can it be pulled too slowly. Look in the left and right mirrors at any time, observe the oncoming cars from behind, slowly change lanes when conditions allow, until you reach the outermost lane, and then press the brake pedal continuously to see if the brakes are really out of order.

If the brakes have some effect, stop the car and call for a tow truck.

If the brakes fail, we have to try to slow down the car by using forced gear reduction (commonly known as gear rushing). If you're in an automatic transmission, try pressing the brake pedal down to force the brakes to reduce the speed to a very low speed, and then push the gear lever to N gear (neutral) to slow down.

R gear in the car forward: the car can not be hung into R gear in high-speed progress, even if you can push the mechanical gear lever to the R position, even if the instrument has shown R, but the actual gear at this time is also on standby in N gear, and the protection mechanism of the gearbox will never make a command to cut into R gear, and the handbrake must not be pulled in place in one step. Pulling the handbrake directly can cause the vehicle to slip, lose control, or even roll over.

If there is a ramp, you can pull the handbrake slightly and control it according to the specific situation.

For manual parking, it is necessary to quickly tighten - quick release - and then quickly tighten the cycle and pull the handbrake to simulate the ABS function until it stops; If it is electronic parking, directly buckle the parking button, electronic parking has a simulated ABS function, for 100 kilometers per hour speed, parking generally has a deceleration effect. If the above methods do not work, use objects on both sides of the road that can cause friction with the tires to reduce the speed of the car and slow it down. As a last resort, in an emergency, you should decisively use the bumper, carriage and other rigid parts of the car to collide with natural obstacles (rocks, trees or dirt slopes) on the side of the road to achieve the purpose of forcibly stopping and escaping.

At this time, you must keep calm, and then hit a double flash to remind other vehicles to see you, and then find an open and safe place to park the car, and be sure to slow down during the process.

If something like this happens suddenly, you should turn off the fire, or just turn off the key, and then call the police in time.

At this time, you should quickly downshift, slowly reduce the speed of the car, and then immediately go to the traffic police, and turn on the double flash, waiting for the traffic police to rescue.

When the automatic transmission brake fails, the driver mainly keeps calm, holds the steering wheel, releases the accelerator pedal to slow down, releases the accelerator pedal, and turns on the double flashing lights.

Find a safe area and pull the handbrake directly, so that you can quickly turn off the ignition, and it will also avoid other accidents, and you must also learn some safe braking techniques.

At this time, you can put down the handbrake and shift to first gear, so that the speed of the car can be slowly reduced.

The first thing to do is to calm down. Don't do it casually. Grasp the steering wheel, release the accelerator pedal, and turn on the hazard warning lights (double flashing lights).

Then look in the left and right rearview mirrors at any time to observe the cars coming from behind. When possible, slowly change lanes until you reach the outermost lane. Then press the brake pedal continuously to see if the brake really fails.

If the brakes have some effect at this time, stop the car and call it a tow truck. Here are some things you can try:1.

Try gear braking. Cars with automatic manual transmission can be changed to manual mode downshift braking; Cars with automatic transmission can first put on "2" gear, and then "L" gear. Remember not to put in the "p" and "r" files, and try not to put in the "n" file.

2.The deceleration of the handbrake is relied upon to force the automatic transmission to downshift due to the slow speed. Remember to pull the handbrake quickly and put it down right away.

The action should be fast, because if the handbrake is forcibly pulled to death, it will cause the handbrake line to break and crack the bridge foundation or the vehicle to lose control. So the car can only force automatic downshift by frequently pulling the handbrake; 3.If none of the above methods work, then the only way to do this is to put safety first and minimize losses as much as possible

Use the side of the car to rub the fence to dissipate yards, or use some collidable objects to stop the vehicle. Be sure not to use the front of the car to collide.

You should quickly choose to release the throttle and find a way to use the clutch to reduce the speed, or you can choose the emergency lane or a place with trees next to it, and try to reduce the speed control.

You should release the throttle and step on the clutch at the first time, constantly downshift and slowly pull the handbrake to achieve the purpose of slowing down, remember not to pull the handbrake to the end at one time, you can also choose the buffer belt to slow down.

If the brakes of the manual transmission car fail, let go of the accelerator pedal as soon as possible and step on the clutch to downshift to achieve the purpose of generating traction from the engine. Constant downshifts and handbrakes can achieve the purpose of deceleration. However, when you pull the handbrake, you can't pull it to death, and you can do it all at once.

Otherwise, there is a lock-up of the rear wheels and the vehicle may lose control again.

If you find that the brakes are out of order, you should drive the car to the side of the road to the ground for friction, forced braking, or putting down the handbrake, which can also play a role in braking.

The most correct way to operate is to press the automatic transmission to the minimum, and then go to a safer place with fewer people, and then issue a series of warnings, so that you can save in time.

You should hold the steering wheel and slow down gradually, because only in this way can you better ensure your driving safety.

You can hold the handbrake all the time, so that the car will gradually slow down and stop. But be sure to hold the steering wheel and don't bend easily.

If the brake of the manual transmission fails, there are many ways to step on the clutch, and the idle speed of the clutch can also be reduced, and the handbrake should be pulled up at this time.

Specifically, first turn the gear into neutral, and then press the clutch all the way down so that the car stops.

It should be parked in the emergency lane in time, hit ** for rescue, brake failure should be slowly forced, and slowly pull the brake to the end.

What is the cause of brake failure in an automatic transmission car? The reasons for car brake failure can be as follows:

1. Failure to maintain the brake system regularly, resulting in too much dust and trapping of impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, excessive dirtiness of the brake oil, etc., caused by air resistance, oil leakage of the brake master cylinder or sub-cylinder, air leakage of the gas storage tank or pipeline interface;

2. There is also the problem of improper operation, which leads to the failure of the parts, such as long-term downhill braking, which will cause the brake pads to generate heat early, the brake hub to carbonize, and the brake function to completely fail;

3. It may also be caused by serious overload, under the effect of gravity acceleration, the inertia of the vehicle is increased, which directly leads to brake failure.

Handling of brake failure of automatic transmission cars: Keep D gear for sale and continue to step on the brakes. Because the foot has left the throttle, under the constraints of the engine, the speed of the car will gradually decrease; Of course there is a process.

Because of the presence of ABS, even if you apply the brakes, the steering wheel can move slightly, avoid obstacles, and stay calm. How to deal with automatic brake failure:1.

When the car suddenly brakes fail while driving, you should calmly and quickly disconnect the high-speed gear to blow the oil, change the high-speed gear to the low-speed gear, and use the traction resistance of the engine to reduce the speed; 2.When changing low gears, the handbrake should be used together, but it should be noted that the handbrake cannot be tightened at one time, nor can it be pulled too slowly; If it is pulled too tightly, it is easy to "lock" the brake disc, which may damage the transmission parts and lose the braking ability; If you pull too slowly, the brake disc will wear out and ablate and lose its braking function; 3.If the danger cannot be ruled out, use objects on both sides of the road that can rub the tires of the wheel bucket to reduce the speed of the vehicle and stop slowly; 4.

As a last resort, in the case of emergency air return, decisively use the bumper, compartment and other rigid parts of the car to collide with natural obstacles (rocks, trees or slopes) on the side of the road, so as to achieve the purpose of forced parking and escape, and reduce the accident loss as much as possible.
