After the engine is turned off, the brake cannot be stepped on, how to stop the car when the engine

If the vehicle suddenly stops while driving, it can immediately descend in a sequential direction, and the gear can be used to slow down.

After a while, the brake can't be stepped on, how to stop the car when the engine is turned off while driving? There must have been a problem with the brakes. It is very dangerous to turn off the engine while driving.

And the brakes don't work. At this time, the eight-pound steering wheel is pinned to stop or hurry up to start the car to see if it can start.

When the car is turned off, the brakes are hard to pressTo put it simply, the main reason is that the car brake needs the engine to work to produce a vacuum, to provide brake assistance, after the engine is turned off, the vacuum required for brake assistance is gone, so the brake can not be stepped on, but this is only limited to automatic transmission cars.

The manual transmission car is different, after the engine is turned off, as long as it is not hung in neutral, the rotation of the wheels can still reverse the engine rotation, as long as the engine rotates, it can continue to produce a vacuum and provide brake assistance. Therefore, when the manual transmission car turns off during driving, do not hang neutral gear, keep the original gear, and just step on the brakes directly, which also gives the engine an anti-drag braking force and makes it easier to stop.

When the vehicle turns off during driving, the vacuum of brake assistance will not be lost immediately, and the brake will not fail immediately, but there is no power assist system, and the brake pedal is very hard to press, and the normal braking effect cannot be achieved. But our top priority is not to hesitate, immediately apply the brakes, use a little more force, and usually the car can be braked.

Don't divide the brake twice, one foot to the end, because the first foot will consume the vacuum, and then the second foot will greatly weaken the braking effect, so you need to be in place at one time, one foot to the end, and you can't choose to use the point brake.

After the car turns off, the brake of the car cannot be stepped on because after the car turns off, the braking force disappears, and the mechanical pump cannot operate, so the braking force cannot be generated, so the brake stone forest is made.

To put it simply, the brake pad of the car must cause a mechanical pump when the engine is working and push towards the brake pad. After the engine is turned off, the vacuum pump value pushed by the brake plate is gone, so the brake plate cannot be pressed, so in the case of the car stalling, you must not only rely on the brake system to brake, but also need the handbrake to cooperate.

What causes the car to always stall?

Generally speaking, the main reason for the stalling of cars is the use of counterfeit and shoddy refined oil. Operationally, automatic transmission cars will be more difficult to check. Once the automatic transmission car is turned off, the main factor is the use of counterfeit and shoddy refined oil, which does not exceed the standard, resulting in carbon accumulation and stalling of the engine.

Engine and computer malfunction. Judging by the mileage, the car has been driving for a long time. The engine and computer can cause stalling failures.

In addition, the failure can come from a faulty fire nipple or high-pressure packaging, resulting in 1 cylinder or multi-steel not ignition, resulting in flameout. But only multi-steel failure without ignition can lead to flameout, so it is very likely, but the probability is not large.

How to check the reason why the car does not catch fire?

Failure of the engine itself. The engine idle motor or the wiring of the idle motor is damaged, or there is a problem with the standby module in the ECU of the engine electronics adjustment control module. The probability of failure of the engine itself holds a high market share among the many factors that cause the car to stall.

The vehicle battery is not charged or damaged, the number of battery cycles expires, or due to the long-term placement of the car, resulting in the battery being idle and not damaged, the loss of battery power may be due to the car turning on the starter motor is not running, the headlights are on for a long time, and high-power vehicles such as high-power interference have been used.

Excessive carbon build-up in a vehicle's engine can also make it difficult to operate. It is likely to be related to the poor quality of refined oil wholesale and the poor sealing of the gas main valve. Faults can be caused by ignition system failures, low-voltage control circuit line connections that are not hot, or high-voltage lines that are powered away.

If the car turns off and can't step on the brakes, it is likely that the booster is damaged, or it may be because the brakes are damaged or the brakes fail, or there may be problems with the vacuum booster of the brakes.

Because the car is turned off, the car will be powered off, and the vacuum booster pump of the car needs electricity to work, so the brakes cannot be used normally at this time. Because the brakes need a vacuum booster pump to work.

This is because after the car is turned off, the power gradually disappears; The reason is that the vacuum in the booster becomes less and less as the car turns off, so the booster equipment for the brakes does not work.

Because all vehicles are configured like this, the brakes cannot be stepped on when the engine is turned off, because the vehicle's system is turned off when the engine is turned off.

I don't know what's going on.

Dear, stepping on the brakes will not automatically turn off the ignition for the following reasons: stepping on the brakes does not automatically turn off 1Vehicles equipped with automatic start-stop function are turned on the start-stop system by default, and suddenly it cannot be used, and the lead spine may be that the automatic start-stop button on the car is pressed by mistake, resulting in the system being closed, check whether the system is closed.

Extended information: As the name suggests, the chain calling pedal is a pedal that restricts power, that is, the pedal of the foot brake (service brake), and the brake pedal is used to slow down and stop. It is one of the five major sail control parts for car driving.

The frequency of use is very high. How the driver's control directly affects the driving safety of the car.

The reason for the brake stall is due to the fact that the engine and transmission are not separated in time due to the brakes being too strong. If it is a self-proclaimed car with a dynamic gear, it may be that the idle stability valve of the car is damaged, which directly causes the idle speed to be controlled by the control valve and cannot be kept working normally.

The car stops when it slows down when it hits the brakes, mainly because the gear is too high, the brake is sudden or the brake is only stepped on, and the clutch is not pressed. Therefore, if the gear is high, the gear should be reduced in time; If the speed is not fast, you should first step on the clutch Qing Qi grip, and then gently apply the brakes, when the pedestrian or non-motorized vehicle is moving forward, there is no need to fully stop.

Generally speaking, in urban road conditions, emergency braking should be avoided as much as possible. Emergency system will not only increase fuel consumption, but also affect the service life of tires. At the same time, when passing through ramps such as bridge decks, pay attention to long-distance braking when going downhill, do not hang into neutral gear, and be sure to slide with gear.

Otherwise, the braking distance will be extended, the braking effect will be affected, and it will also be detrimental to safety.

In snow and ice conditions, do not use emergency braking. You can engage in low gear, release the throttle, and use engine traction to brake. In order to increase the friction coefficient of the road surface, snow chains can be hung; If it's grass, it's not as slippery as ice and snow, so in general, it's enough to run at a suitable speed.

If you need to brake, you should have foresight and judgment to prevent you from encountering obstacles or falling into soft mud. (Photo by Chen Miaoling) @2019

Some new drivers thought that the engine was caused by braking too hard and the engine and transmission were not separated in time, so they did not pay attention to it. But later, when the car started in place, the engine could not idle normally and was prone to stalling.

Automatic transmission models will not easily stall, and manual transmission models may often stall due to the low level of driving, but it is not excluded that automatic transmission cars will not stall, the main reason is the use of inferior fuel (many gas stations sell impure oil in order to obtain huge profits) resulting in engine carbon deposition and stalling.

2. In addition, the reason for the stalling of the new car (automatic transmission) is mainly caused by the lack of skillful driving skills, and another possibility is the problem of the car engine or oil circuit, but for the new car, the problem of the engine itself is less likely, and most of the reason is the problem of the oil circuit.

3. Finally, for old models, the reason for the stalling is not enough driving skills, that is, the use of substandard oil to make the engine collect carbon and other causes of stalling.

It should be a place where there is a leak in the vacuum boost, and when the air enters the intake when the brake is stepped on, the mixture becomes thinner instantly, which leads to stalling, and the throttle is too dirty.

If it's not a driving problem, it should be that the throttle is dirty.

This is related to the braking principle for the following reasons:

1. The braking brake is assisted by the vacuum of the engine intake pipe;

2. The higher the vacuum, the lighter and faster the braking;

3. After the engine is turned off, there is no vacuum source, and there is no power assist for braking;

4. Therefore, after the engine is turned off, the brakes will become stiff and cannot be stepped on.

Here's why:1. Because after the ignition is turned off, there is no vacuum in the engine manifold, so the brake vacuum booster pump does not work, which is like the steering is difficult to impress after the car is turned off, because in the same way, the steering power pump does not have enough vacuum to utilize.

2。Usually the first foot brake can be pressed, and it feels like the gas is squeezed out, and the back will become harder and harder.

Today's brakes are all hydraulic-assisted, not the kind of tensile steel wires found on bicycles. Therefore, after the engine is turned off, the hydraulic oil does not work, and the hydraulic oil brake cannot be stepped on. Just put the fire on the brake pedal and it will come up.

The fact that it's normal for a car to hit the brakes when it's turned off is easy to understand because it's already out of power. Among them, the real air booster pump is the key, because because of its existence, it is very easy for us to use the brakes when driving, and it is also the reason why we can't go down after the ignition is turned off.

1. The reason for the sudden stalling of all cars while driving:

1. Circuit fault;

2. Flameout caused by short circuit of low-voltage line: intermittent flameout; 3. Device failure: it can start at first, turn off after a while, and then start again, and then turn off again;

4. Oil circuit failure; The gasoline pump was damaged, the oil line was ruptured, the carburetor inlet was clogged, and the fuel tank ran out of oil.

5. There is a problem with the ignition system and the explosion-proof system for engine overheating.

When it is found that after the ignition is turned off, according to the road conditions at the time, if there is no emergency, you can slowly step on the brakes to prevent the tail light, after the speed is reduced, slowly play the direction, drive to the roadside lane, pay attention, the brake should be stepped on all the time, the power from small to large, do not step on it and then loosen, and then go to the pedal, which will lead to the only remaining vacuum is also consumed, and then step on it can not be stepped on, park the car on the side of the road, turn on the four flashing lights, place the tripod, and hit the ** rescue trailer.

1. After the ignition is turned off, the brake is stepped on several times, causing the vacuum in the brake booster pump to disappear;

2. The booster pump does not work when the ignition is off, then try to re-ignite and press the brake pedal hard, and wait until it is started to return to normal.

In addition, you need to pay attention to the correct braking method as follows:

1. When driving at low speed, you can encounter an emergency in front of you and brake urgently, and step on the brake pedal, but you can't do it at high speed to avoid the vehicle sliding and rollover.

2. You can brake slowly under normal road conditions, release the accelerator pedal while pressing the clutch pedal, switch the low-speed gear, lift the clutch pedal after the speed is lowered, and press the brake pedal until it stops.

3. In the case of high temperature under the long slope in the mountainous area or continuous braking, the intermittent braking of the brake pedal can be effectively avoided by intermittently stepping down and relaxing the brake pedal.

It's not okay to ask questions.

Ask the green sign above.

It means please press the brake pedal".

Volkswagen, right? Ask questions.

Now the brakes are all oil-powered, so the hydraulic oil does not work after the engine is turned off, and the hydraulic oil brake will naturally not be stepped on. Just put the fire on the brake pedal and it will come up.

Cars are generally electric or vacuum-assisted, and after the car is turned off, the engine has no power output, so the power fails, so that the brakes and clutches can not be stepped on, in the vacuum brake car, some manual transmission cars will also have no power assist when in neutral gear, therefore, the vacuum brake car is not allowed to use neutral gear (such as neutral slide) during driving.

Precautions for the car shutdown process:

Turn on the air conditioner and turn off the engine:

In fact, if the air conditioner is turned off, there is no doubt that the air conditioner will start together when it is started, and the engine in ancient times will be overloaded to work, and over time, the engine will cause damage. So before you turn off the fire, you might as well turn off the air conditioner!
