If you forget to put down the handbrake and drive 100 meters, how much damage will it do to the car?

Forget to let go of the handbrake, this thing is probably a person has done, especially just got a driver's license for a short time, the previous car, are mechanical handbrakes, it is indeed a big pain for female drivers, it is easy to pull up, put it down really takes a lot of effort, now the words are different, a little better car, are equipped with electronic handbrake.

What happens if you forget to let go of the handbrake?

In the case of mechanical handbrakes, if you forget to put the handbrake, this problem may be more serious. First of all, the principle of mechanical handbrake and electronic handbrake is the same. Both of them provide braking by creating friction through the compression of brake discs and brake pads.

The mechanical handbrake is pulled by hand through leverage, and the wheels are controlled by the steel rope, which is the most direct, when the mechanical handbrake is pulled up, you directly drive the car on the road, and the rear wheels of the car will not turn, that is to say, the front wheels drag the rear wheels to run. Then think about what this picture looks like.

Needless to say, the tires were directly pressed to the ground and rubbed, leaving a long tail along the way, and if they were not detected in time, they would have burned the tires directly. Brake pads and brake discs are seriously worn. The steel rope was badly deformed, lost its elasticity, and in addition, the burden on the engine was increased due to the non-work of the rear wheels.

Fuel consumption will also increase, so if you feel that the power can't keep up, the throttle is too heavy, and you find smoke coming from behind, stop quickly to see if the handbrake light on the dashboard is on. Of course, if you only drive 100 meters, it doesn't really matter, and the car still has this tolerance.

If you have an electronic parking brake, you don't need to worry about this problem, even if you don't let go of the electric parking brake, as long as you step on the accelerator, the electronic parking brake will automatically unlock. The electronic parking brake is automatically released, and most of the electronic parking brake types will automatically help us turn on the electronic parking brake after we stop the engine and unfasten the seat belt.

And when we get in the car again, fasten the seat belt, and the door is closed, as long as we step on the accelerator, the automatic handbrake will also be automatically released. In addition, if you accidentally pull up the electronic parking brake at high speed, the electronic parking brake will not respond immediately, but will only work when the speed is close to stopping (usually less than 10 km h).

How far can you drive if you forget to let go of the handbrake? What harm does it do to the car?

If you forget to put down the handbrake and drive 100 meters, the damage to the car is not very great, because although the brake disc has been rubbing for 100 meters, it will not cause heating or cracking.

Very big. Because if you don't let go of the handbrake, the wheels will not turn, which will cause great damage to the engine and wheels, so it will hurt the car very much.

Very large, which will cause the brake pads to rub against the tires all the time, causing the brake pads to overheat and may be scrapped early.

Forget to put down the handbrake and drive 100 meters, the damage to the car is actually not very large, because the distance is relatively short, if you drive like this for a long time, the damage to the car is still relatively large, so you must not make a mistake before getting in the car. In addition, you should also visit the car for a week before driving, which can reduce a lot of accidents. <>

First, the damage to the car is very small

When you learn to drive, you should remember to get on the car and wear a seat belt and put the handbrake, these two things are essential, if you forget it, it may also bring some unexpected traffic accidents, forget to put down the handbrake and drive 100 meters will not cause harm to the car. I want to tell you that because this distance is relatively short, the damage is not very large. The damage he caused to the car can be negligible, just think of himself as if he did an emergency brake, but don't forget it in the future.

Second, be sure to check around the car for a week before getting on the bus

If the towing distance is relatively large, the tire will also wear, and it may also affect the brake cylinder. We must drive strictly in accordance with the way of driving, don't worry, whether you are a novice or an old driver, you must be vigilant, novice drivers are recommended to find someone to accompany when driving for the first time, so that they can remind, so that you will not be at a loss. We sometimes forget to let go of the handbrake, at this time we have to feel whether your body is uncomfortable, and listen to whether there is any sound, if there is any, you can see, is it not in place?

Be sure to check around the car before driving, this week's inspection can sometimes reduce a lot of trouble for you, because there is a blind spot in the car, really, if someone is in the blind spot, we have to bear most of the responsibility, or even all of the responsibility. It also reminds everyone to obey the traffic rules when driving, some driver's license rules have changed, and we must also take a look at the relevant announcements in time.

The injury is particularly serious, it may cause damage to the belt, may cause serious scratches on the tire, may affect the normal braking of the engine, and may cause the engine to stall.

The damage to the car is very large, because it is likely to cause very serious wear and tear on the car's engine, and it may also lead to a decrease in the service life of the car and damage the car's parts.

The damage to this car is really very big, if you don't put down the handbrake and then drive, it may cause the wheels of the car to wear and tear all the time.

The damage is very large, which has to be done to the wear and tear of the engine and gears quite severely, which may eventually lead to the vehicle not being able to drive normally.

How can you drive if the electronic handbrake is not turned off, the electronic handbrake is different from the mechanical handbrake, the electronic handbrake is automatically turned on as long as you turn off the engine (some models do not support it), as long as it is started, remember the seat belt, and it will be automatically lifted as soon as you step on the accelerator (all the models of the electronic handbrake I know support it).

And the electronic handbrake if you don't send the seat belt is not lifted, the big foot throttle is not gone at all, let alone drive 1 km, the normal is to step on the accelerator automatically released (must send the seat belt), otherwise the convenience of the electronic handbrake is meaningless, if you remember that the seat belt is not turned off, the electronic handbrake can also be driven 1 km, it can only be your car electronic handbrake has a problem, so it hurts to drive the car.

How much will make a difference. If you don't let go of the handbrake for 20 kilometers, the brake pads will rub against the brake drum (disc) for a long time to produce high temperature, and in serious cases, the brake pads or brake drum (disc) will be burned, and the high temperature will change the structure of the brake pads, weaken the braking force, and even lead to brake failure.

The impact of driving without letting go of the hand brake:

1. Pull the handbrake to drive, the most direct impact is that the brake disc will accelerate wear and tear and the brake pads will harden after heating, and the handbrake cable will be elongated, which will lead to a decrease in braking performance.

2. If you pull the handbrake for a long time to drive, it may also cause the brake cylinder to be crushed, the brake fluid leaks, and the brake fluid temperature is too high, resulting in the complete loss of the brake function, which is very dangerous.

Emergency measures: If you find that you are driving with a handbrake while driving, and there is a serious burnt smell and smoke coming from the rear of the car, the owner should immediately slow down, brake, and put down the handbrake. At this time, you should not continue to move forward, you should park the car on the side of the road, wait for the temperature of the car to cool down, and then carefully observe if there is anything else.

Don't just drop the handbrake and keep driving while the car is still hot, it's extremely dangerous.

Correct method: Running with a handbrake will cause a lot of loss on the brakes. To develop correct driving habits, before driving to see whether the handbrake has been released, but also pay more attention to the dashboard, the information displayed by the dashboard is more comprehensive, observe the information of the dashboard at any time, pay attention to the warning lights, so that you can avoid driving with the handbrake.

It is not much damage to the car, the brake pads may wear out, it is recommended to go to the car repair shop to check it, if the wear is bad, replace it, under normal circumstances, it is fine, just as it is normal braking for 20 kilometers, no big deal.

There must be damage, the first is the braking system. Pull the brake for 5 minutes, the temperature of the brake pads will be very high, and if you drive for a long time, the brake locking system will be damaged. At this time, be sure not to pour it with cold water.

Otherwise, it is deformed. Afterwards, be sure to check the brake pads and discs.

Remember, when driving in the future, especially on long distances, be sure to take a look at the tips on the dashboard!!

It's common to forget to put down the handbrake and drive 100 meters. It is estimated that more than 90% of car owners have this experience. Even if you drive a lot and become an old driver when you grow up, you will occasionally have the stinky problem of driving without letting go of the handbrake.

To be honest, when I first started driving, I didn't let go of the brakes and ran 3 kilometers. The handbrake warning light appears on the instrument panel, while the vehicle sounds an alarm. I wonder why the vehicle is making noise.

The seat belt was fastened, and when I got home, I found that the handbrake was not loose. No, the car still traveled 150,000 kilometers intact. Don't panic, pick up your phone and take a picture**, and send it to Bian Xiao for you to see!

Let's start with the vehicle's handbrake system.

Handbrake systems are divided into electronic handbrakes and mechanical handbrakes. When driving with the handbrake for a long time, different handbrake systems have different degrees of damage to the vehicle.

Mechanical handbrake. The manipulator brake is a brake caliper that is connected to the rear wheels of the vehicle by means of a steel wire or similar mechanism. When the handbrake is pulled, the caliper of the handbrake system compresses the brake pads under the force of the cable, so as to realize the parking function.

If the owner is driving with the mechanical brakes pulled up, there will be severe wear between the brake pads and the brake discs. In this case, the hand brake system of the manual transmission vehicle will be damaged.

In addition, when we hold the handbrake for a long time, the steel wire of the handbrake will bear a certain force for a long time, and the steel wire of the handbrake will be plastically deformed for a long time; In addition, there is a return spring in the handbrake system. When the handbrake is pulled, the return spring always works. When the handbrake is released, the spring will return to its original length, and plastic deformation will occur after long-term use.

So, our handbrake system will get worse. In the new car phase, better braking can be achieved when the handbrake is pulled to 60%. But as the handbrake system deteriorates, the length of the wire becomes longer, the brake pads wear out, and the handbrake needs to be pulled to 80% to achieve better braking.

As the vehicle is used, the parking brake effect of the handbrake system slows down, and this only gets worse when we pull the handbrake up.

The so-called electronic handbrake is a technology that realizes parking brake through electronic control, which is composed of electronic buttons, motors, brake pads, etc. of the handbrake. When the owner presses the electronic button, the motor will apply braking force to brake the vehicle, and when the owner pulls the electronic button, the power is released.

Currently, electronic parking brakes are generally used in conjunction with autohold. When the owner steps on the accelerator to drive, the electronic parking brake will automatically release. When the owner stops, the electronic parking brake works automatically.

This braking system is very intelligent and can automatically determine whether to release or brake based on the state of the vehicle.
